refactor(apify): move Actor tools into bundled plugin

Re-shelve the three Apify tools from core into plugins/apify/, matching
the Spotify plugin pattern for optional third-party SaaS integrations.
tools/ is reserved for foundational capabilities; third-party service
integrations live in plugins/.

- plugins/apify/{__init__,tools,client}.py + plugin.yaml + README
  (kind: backend, auto-loads; registers via ctx.register_tool())
- remove apify_* from _HERMES_CORE_TOOLS in toolsets.py
  (TOOLSETS["apify"] entry kept, mirroring spotify)
- tests moved tests/tools/test_apify_tool.py -> tests/plugins/test_apify.py,
  import paths updated (34 tests pass)
- add JanHranicky to AUTHOR_MAP in scripts/release.py (CI gate)

The tools_config.py / config.py / lazy_deps.py / pyproject.toml setup +
config UX from the original commit is retained unchanged.

 **The self-improving AI agent built by [Nous Research](https://nousresearch.com).** It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.

+
+اگر آپ کے پاس پہلے سے گٹ (Git) انسٹال ہے، تو انسٹالر اسے شناخت کر لیتا ہے اور اسے ہی استعمال کرتا ہے۔ بصورت دیگر آپ کو صرف ~45MB کے MinGit ڈاؤنلوڈ کی ضرورت ہوگی — یہ آپ کے سسٹم کے گٹ پر کوئی اثر نہیں ڈالے گا۔

+## API-کیز اکٹھی کرنے سے بچیں — Nous Portal
+
+ہرمیس آپ کے پسندیدہ پرووائیڈر کے ساتھ کام کرتا ہے — یہ چیز تبدیل نہیں ہو رہی۔ لیکن اگر آپ ماڈل، ویب سرچ، امیج جنریشن، TTS، اور کلاؤڈ براؤزر کے لیے پانچ الگ الگ API کیز جمع نہیں کرنا چاہتے، تو **[Nous Portal](https://portal.nousresearch.com)** ان سب کو ایک ہی سبسکرپشن کے تحت کور کرتا ہے:
+
+- **300+ ماڈلز** — ان میں سے کوئی بھی ماڈل `/model <name>` کے ذریعے منتخب کریں
+- **ٹول گیٹ وے (Tool Gateway)** — ویب سرچ (Firecrawl)، امیج جنریشن (FAL)، ٹیکسٹ ٹو سپیچ (OpenAI)، کلاؤڈ براؤزر (Browser Use)، یہ سب آپ کی سبسکرپشن کے ذریعے چلتے ہیں۔ کسی اضافی اکاؤنٹ کی ضرورت نہیں۔
+
+نئی انسٹالیشن کے بعد بس ایک کمانڈ کی ضرورت ہے:
+
+<div dir="ltr">
+
+```bash
+hermes setup --portal
+```
+
+</div>
+
+یہ آپ کو OAuth کے ذریعے لاگ ان کرواتا ہے، Nous کو آپ کا پرووائیڈر مقرر کرتا ہے، اور ٹول گیٹ وے کو آن کر دیتا ہے۔ `hermes portal info` کمانڈ استعمال کر کے آپ کسی بھی وقت چیک کر سکتے ہیں کہ کون کون سی سروسز منسلک ہیں۔ مکمل تفصیلات [Tool Gateway دستاویزات کے صفحے](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway) پر موجود ہیں۔
+
+آپ اب بھی کسی بھی ٹول کے لیے اپنی مرضی کی API کیز استعمال کر سکتے ہیں — گیٹ وے ہر سروس کے لیے الگ الگ کام کرتا ہے، ایسا نہیں کہ یا تو سب کچھ استعمال کریں یا کچھ بھی نہیں۔

+اگر آپ OpenClaw سے منتقل ہو رہے ہیں، تو ہرمیس آپ کی سیٹنگز، یادیں (memories)، مہارتیں (skills)، اور API کیز کو خود بخود امپورٹ کر سکتا ہے۔
+
+**پہلی بار سیٹ اپ کے دوران:** سیٹ اپ وزرڈ (`hermes setup`) خود بخود `~/.openclaw` کو پہچان لیتا ہے اور کنفیگریشن شروع ہونے سے پہلے مائیگریٹ (migrate) کرنے کا آپشن دیتا ہے۔
+
+**انسٹالیشن کے بعد کسی بھی وقت:**
+
+<div dir="ltr">
+
+```bash
+hermes claw migrate              # انٹرایکٹو مائیگریشن (مکمل پری سیٹ)
+hermes claw migrate --dry-run    # جائزہ لیں کہ کیا کیا مائیگریٹ ہوگا
+hermes claw migrate --preset user-data   # حساس معلومات (secrets) کے بغیر مائیگریٹ کریں
+hermes claw migrate --overwrite  # موجودہ متصادم فائلوں کو اوور رائٹ کریں
+```
+

+- **ورک اسپیس کی ہدایات** — AGENTS.md (`--workspace-target` کے ساتھ)
+
+تمام آپشنز دیکھنے کے لیے `hermes claw migrate --help` استعمال کریں، یا انٹرایکٹو ایجنٹ کی مدد سے مائیگریٹ کرنے کے لیے `openclaw-migration` سکل کا استعمال کریں (جس میں ڈرائی رن (dry-run) پریویوز شامل ہیں)۔

+"""Per-turn setup for ``run_conversation`` (the turn prologue).
+
+``run_conversation`` opened with ~470 lines of straight-line setup before the
+tool-calling loop ever started: stdio guarding, runtime-main wiring, retry-counter
+resets, user-message sanitization, todo/nudge-counter hydration, system-prompt
+restore-or-build, crash-resilience persistence, preflight context compression, the
+``pre_llm_call`` plugin hook, and external-memory prefetch.
+
+All of that is *prologue* — it runs once per turn, has no back-references into the
+loop, and produces a fixed set of values the loop then consumes. ``TurnContext``
+captures those produced values; ``build_turn_context`` performs the setup work and
+returns one. ``run_conversation`` is left to unpack the context and run the loop,
+shrinking the orchestrator by the full prologue.
+
+The builder still mutates ``agent`` heavily (counters, thread id, cached prompt,
+session DB) exactly as the inline code did — those side effects are the point. The
+``TurnContext`` it returns carries only the *locals* the loop reads back.
+
+Behavior is identical to the original inline prologue; this is a pure
+move-and-name refactor with no semantic change.

+"""Per-attempt recovery bookkeeping for the conversation turn loop.
+
+The inner retry loop in ``run_conversation`` (``while retry_count <
+max_retries``) makes several distinct recovery attempts on a single model API
+call: a credential-pool 429 retry, a per-provider OAuth refresh (codex,
+anthropic, nous, copilot), a long-context compression restart, a length-
+continuation restart, and a handful of format-recovery branches (thinking-
+signature stripping, multimodal-tool-content stripping, llama.cpp grammar
+fallback, image shrink, invalid-encrypted-content, 1M-beta header).
+
+Each of those branches is guarded by a one-shot boolean so it fires at most
+once per attempt. They used to be ~16 bare ``*_attempted`` / ``has_retried_*``
+/ ``restart_with_*`` locals declared inline before the loop and threaded
+through its 2,400-line body. ``TurnRetryState`` collapses them into one object
+the loop mutates in place (``state.codex_auth_retry_attempted = True``), giving
+the recovery bookkeeping a single named, testable home.
+
+Loop-control variables (``retry_count``, ``max_retries``,
+``max_compression_attempts``) intentionally stay as plain locals — they are the
+``while`` mechanics, not recovery bookkeeping, and putting them on the object
+would add indirection without clarifying anything.
+
+This module is dependency-free so it can be unit-tested in isolation and
+imported by the turn loop without an import cycle.

+# Desktop Design System
+
+Conventions for the Electron desktop app (`apps/desktop`). Read this before
+adding a component, overlay, or style. The rule of thumb: **one source per
+concern, tokens over literals, flat over boxed.** If you reach for a raw color,
+a one-off shadow, a bespoke button, or a hardcoded `px-*` on a control — stop,
+there's already a primitive for it.
+
+## Principles
+
+1. **Flat, not boxed.** No card-in-card, no divider borders inside a panel.
+   Group with whitespace and a single hairline, never nested rounded boxes.
+2. **Borderless + shadow for elevation.** Overlays float on `shadow-nous` + a
+   `--stroke-nous` hairline, not hard borders.
+3. **One primitive per concern.** One `Button`, one set of control variants,
+   one `SearchField`, one `Loader`, one `ErrorState`. Migrate onto them; don't
+   fork.
+4. **Tokens, not literals.** Reference CSS vars (`--ui-*`, `--shadow-nous`,
+   `--theme-*`), never raw hex / ad-hoc rgba in components.
+5. **Style lives in the primitive.** Variants and sizes own padding, radius,
+   color, chrome. Call sites pass a `variant`/`size`, not `className` overrides
+   that re-specify those.
+
+## Surfaces & elevation
+
+Every overlay / dialog / toast (boot-failure, install, notifications,
+model-picker, onboarding, prompt-overlays, updates, base `Dialog`) uses:
+
+```
+shadow-nous           /* downward-weighted, layered contact→ambient falloff */
+border-(--stroke-nous) /* currentColor hairline, theme-adaptive */
+```
+
+Both are CSS vars in `src/styles.css` — tune in one place, everything inherits.
+Don't add per-overlay `shadow-[…]` or `border-(--ui-stroke-secondary)`
+one-offs; if elevation needs to change, change the token.
+
+## Stroke & color tokens
+
+| Token | Use |
+| --- | --- |
+| `--ui-stroke-primary…quaternary` | hairlines, in descending strength |
+| `--ui-stroke-tertiary` | the default in-panel divider / list hairline |
+| `--stroke-nous` | the overlay hairline (pairs with `shadow-nous`) |
+| `--ui-text-primary / -secondary / -tertiary` | text hierarchy |
+| `--ui-bg-quaternary` | soft control fill (secondary button) |
+| `--chrome-action-hover` | hover fill for quiet controls |
+| `--theme-primary`, `--ui-accent` | brand/accent |
+
+Never hardcode `border-gray-*`, `bg-white`, `text-black`, etc. The white tile in
+`BrandMark` is the one sanctioned literal (the mark needs a fixed backdrop).
+
+## Buttons — one component
+
+`src/components/ui/button.tsx` is the single source. Pick a `variant` + `size`;
+do **not** pass `h-*`, `px-*`, `py-*`, or icon-size overrides.
+
+**Variants:** `default` (primary), `destructive`, `secondary` (soft fill —
+the default non-primary look), `outline` (transparent + 1px inset ring, no
+fill/shadow), `ghost`, `link`, `text` (boxless quiet inline — "Cancel",
+"Clear"), `textStrong` (bold underlined inline affordance — "Change",
+"Open logs").
+
+**Sizes:** `default`, `xs`, `sm`, `lg`, `inline` (flush, zero box — for buttons
+that sit inside a heading/sentence; replaces `h-auto px-0 py-0`), and the icon
+family `icon` / `icon-xs` / `icon-sm` / `icon-lg` / `icon-titlebar`.
+
+Notes:
+- Text buttons are square (no radius) and sized by padding + line-height (no
+  fixed heights). Only icon buttons carry the shared 4px radius.
+- SVGs inherit `size-3.5` (`size-3` at `xs`). Don't re-set icon size.
+- Polymorph with `asChild` when the button must render as a link/Slot.
+
+## Form controls
+
+- **`controlVariants`** (`src/components/ui/control.ts`) is the shared shape for
+  `Input` / `Textarea` / `SelectTrigger`. New text-entry controls compose it.
+- **`SearchField`** — borderless, underline-on-focus, auto-width. The only
+  search input. Don't build boxed search bars; don't wrap it in a bordered tile.
+  Empty lists hide their search field.
+- **`SegmentedControl`** — the choice control for small mutually-exclusive sets
+  (color mode, tool-call display, usage period). Replaces radio piles and
+  pill rows.
+- **`Switch`** (`size="xs"`) — bare, with `aria-label`. No bordered text wrapper.
+
+## Layout
+
+- **Gutters:** `PAGE_INSET_X` (`src/app/layout-constants.ts`) for page side
+  padding; `PAGE_INSET_NEG_X` to bleed a child to the edge. Don't hardcode
+  `px-6`/`px-8` on pages.
+- **Master/detail overlays:** `OverlaySplitLayout` + `OverlaySidebar` /
+  `OverlayMain`. Cron, profiles, etc. ride this — don't rebuild a titlebar
+  shell.
+- **Rows:** `ListRow` (settings `primitives.tsx`) for label/description/action
+  rows. Flat, flush-left; no per-row indentation that fights flush headers.
+- **No dividers between rows** unless the list genuinely needs them; prefer
+  spacing. When you do need one, it's a single `--ui-stroke-tertiary` hairline.
+
+## Feedback & empty/error/loading states
+
+- **Loading:** `Loader` (`src/components/ui/loader.tsx`) — animated math/ascii
+  curves (`lemniscate-bloom` for long ops). Never ship the literal text
+  "Loading…".
+- **Errors:** `ErrorState` + the canonical `ErrorIcon` (no bg chip). One look
+  for the React boundary, in-dialog errors, and the boot-failure banner. Pass
+  nodes for title/description so Radix `DialogTitle`/`Description` can flow
+  through for a11y.
+- **Logs:** `LogView` — no bg, hairline border, tight padding, small mono.
+  Every place we surface raw logs uses it.
+- **Empty:** `EmptyState` / `EmptyPanel` — don't hand-roll centered empties.
+
+## Iconography & brand
+
+- **`Codicon`** is the icon set. No mixing icon libraries inline.
+- **`BrandMark`** (`src/components/brand-mark.tsx`) is the brand glyph — the
+  `nous-girl` mark on a white tile, softly rounded, identical in light/dark.
+  It replaced scattered Sparkles glyphs in updates / onboarding / about. Use it
+  for hero/brand moments; don't reintroduce decorative star/sparkle icons.
+
+## Motion
+
+- Quick, functional transitions (~100ms on controls). Respect
+  `prefers-reduced-motion` for anything beyond a fade.
+- Choreographed exits (e.g. onboarding's "matrix" fade-down) stagger per-element
+  then settle the surface — the outer container's fade is *delayed* so it
+  doesn't swallow the inner animation. Don't let a global fade race the detail.
+
+## i18n
+
+- Every user-facing string goes through `useI18n()` (`src/i18n/context.tsx`).
+  No literals in JSX.
+- **Update all locales together** — `en`, `ja`, `zh`, `zh-hant`. A string change
+  in `en.ts` that skips the others is a regression (drifted punctuation,
+  stale labels). Keep trailing-punctuation and tone consistent across all four.
+
+## State (TypeScript)
+
+Mirrors the repo TS style (see root `AGENTS.md`):
+
+- Shared/cross-component state → small **nanostores**, not prop-drilling.
+  Each feature owns its atoms; shared atoms live in `src/store`.
+- Rendering components subscribe with `useStore`; non-render actions read with
+  `$atom.get()`.
+- Colocated action modules over god hooks. A hook owns one narrow job.
+- Keep persistence beside the atom that owns it. Route roots stay thin.
+- Prefer `interface` for public props; extend React primitives
+  (`React.ComponentProps<'button'>`, `Omit<…>`).
+
+## Affordances
+
+- `cursor-pointer` at the primitive level (Button, dropdown/select) — don't
+  hardcode it per call site.
+- Global focus-ring reset; titlebar actions have no active-background state.
+- `Esc` closes every dismissable overlay/dialog (install/onboarding excluded);
+  close is an x-icon, not the word "Close".
+
+## Before you add something — checklist
+
+- [ ] Reuse a primitive (`Button`, `SearchField`, `SegmentedControl`,
+      `ListRow`, `Loader`, `ErrorState`, `LogView`) instead of forking one?
+- [ ] Tokens (`--ui-*`, `shadow-nous`, `--stroke-nous`) — zero raw colors /
+      one-off shadows?
+- [ ] No `className` overriding a primitive's padding / size / radius / chrome?
+- [ ] Overlay uses `shadow-nous` + `border-(--stroke-nous)`, no hard border?
+- [ ] Flat — no card-in-card, no gratuitous row dividers?
+- [ ] All four locales updated for any new/changed string?
+- [ ] `cursor-pointer`, focus ring, and `Esc`-to-close behave?

+ *   - 'full' → remove everything: GUI + agent + all user data.
+ *              `hermes uninstall --full --yes`
+ *
+ * Why a detached cleanup script: 'lite'/'full' delete the very venv the

+ * app bundle (locked on macOS/Windows while the process is alive). So we hand
+ * the work to a detached child that waits for this app's PID to exit, runs the

+/**
+ * Live WebSocket validation for the remote-gateway "Test remote" button.
+ *
+ * Background: the desktop boot does two independent things to a remote gateway:
+ *
+ *   1. The MAIN process hits ``GET /api/status`` over HTTP (token in a header)
+ *      to confirm the backend is up. This is what "Test remote" historically
+ *      checked, and what the boot logs print as "Remote Hermes backend is
+ *      ready".
+ *   2. The RENDERER then opens a live WebSocket to ``/api/ws`` (credential in a
+ *      query param) via ``gateway.connect()``. The chat surface only works once
+ *      THIS succeeds.
+ *
+ * Those two paths use different processes, transports, and credentials, and the
+ * server applies extra guards to the WS upgrade that the HTTP status route never
+ * sees (Host/Origin checks, ws-ticket/token auth, peer-IP checks). So a gateway
+ * can pass the HTTP status check yet reject the WebSocket — which surfaces to
+ * the user as a green "Test remote" followed by an opaque "Could not connect to
+ * Hermes gateway" on the boot overlay.
+ *
+ * This module performs the second half of the check: it actually opens the WS
+ * URL and confirms the upgrade is accepted (and isn't immediately torn down by
+ * a post-upgrade auth rejection). The ``WebSocketImpl`` is injectable so the
+ * unit tests can drive the handshake without a real socket; in production the
+ * caller passes the Node/Electron global ``WebSocket``.
+ */
