feat(desktop+gateway): remote media relay — attach images/PDFs and display gateway images over the network

Desktop connected to a remote gateway can now attach images and PDFs and
display agent-written images. Previously the desktop passed a LOCAL file path
to image.attach; on a remote gateway that path doesn't exist, so the image was
silently dropped ("skipped unreadable path") and the vision model never saw it.
The reverse direction was also broken — images the agent wrote on the gateway
rendered as dead links in the remote client.

Gateway (tui_gateway/server.py):
- image.attach_bytes: base64 byte upload written into the gateway's own images
  dir and queued via the existing native-image-attach pipeline. Magic-byte
  extension sniffing, data-URL prefix + whitespace tolerance, 25 MB cap,
  structured error codes. Accepts content_base64/filename (canonical) and
  data/ext (older-desktop aliases).
- pdf.attach: renders each page to PNG via pdftoppm (poppler-utils) at 150 DPI
  and queues the pages as images; 50 MB / 25-page caps. Accepts host path or
  base64 upload.
- Shared helpers (_decode_attach_base64, _sniff_image_ext, _queue_attached_image)
  so the two methods and the existing image.attach don't duplicate logic.

Gateway (hermes_cli/web_server.py):
- GET /api/media: returns a gateway-local image as a base64 data URL so remote
  clients can display it. Auth-gated like every /api route, extension
  allowlist + size cap, AND confined to the gateway's own media roots
  (images/screenshots/cache, resolved symlink-safe) so an authed caller can't
  read image-extension files anywhere on disk.

Desktop (apps/desktop):
- syncImageAttachmentsForSubmit uploads bytes via image.attach_bytes when the
  connection mode is 'remote'; the local fast path is unchanged.
- media.ts gains isRemoteGateway() + gatewayMediaDataUrl(); directive-text and
  markdown-text fetch images over /api/media in remote mode.

Consolidates the competing remote-media PRs (#38876, #40317, #21908, #39437)
into one coherent implementation, taking the strongest parts of each and adding
shared-helper cleanup plus the /api/media root-confinement hardening on top.
The per-profile gateway switching from #38876 is intentionally left out as a
separable feature. TUI file uploads (#40492) remain a separate surface.

Tested: 11 new tui_gateway tests + 5 /api/media endpoint tests + desktop
media.remote unit tests; full tui_gateway + web_server suites green (472
passed); tsc -b clean; E2E verified the full attach→disk→queue and
gateway-path→data-URL display round-trip plus the out-of-root security block.

+# 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?

+/**
+ * desktop-uninstall.cjs
+ *
+ * Pure, electron-free helpers for the desktop Chat GUI uninstaller. These map
+ * the three user-facing uninstall modes to the `hermes uninstall` CLI flags,
+ * resolve the running app bundle/exe so a detached cleanup script can remove
+ * it after the app quits, and build that cleanup script for each OS.
+ *
+ * Kept standalone (no `require('electron')`) so it can be unit-tested with
+ * `node --test` — same pattern as connection-config.cjs / backend-probes.cjs.
+ * main.cjs requires these and wires them into the electron-coupled IPC layer.
+ *
+ * The three modes mirror the CLI's options exactly:
+ *   - 'gui'  → remove ONLY the Chat GUI, keep the agent + all user data.
+ *              `hermes uninstall --gui --yes`
+ *   - 'lite' → remove the GUI + agent code, KEEP user data (config / sessions
+ *              / .env) for a future reinstall. `hermes uninstall --yes`
+ *   - 'full' → remove everything: GUI + agent + all user data.
+ *              `hermes uninstall --full --yes`
+ *
+ * Why a detached cleanup script: 'lite'/'full' delete the very venv the
+ * `hermes` command runs from, and every mode may need to delete the running
+ * 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
+ * Python uninstall, then removes the app bundle — then the app quits. Same

+/**
+ * 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``.
+ */
+
+const DEFAULT_CONNECT_TIMEOUT_MS = 10_000

+// post-handshake closes the socket almost immediately. Wait a short grace

+ * before-pack.cjs — electron-builder beforePack hook.
+ *
+ * Removes any stale unpacked app directory (`appOutDir`) before
+ * electron-builder stages the Electron binaries into it.
+ *
+ * WHY THIS EXISTS
+ * ---------------
+ * electron-builder's final packaging step copies the stock `electron`
+ * binary into `release/<platform>-unpacked/` and then renames it to the
+ * product name (`Hermes`). If a PREVIOUS `npm run pack` was interrupted
+ * (Ctrl-C, OOM kill, crash, full disk) the unpacked directory is left in a
+ * corrupted partial state: it keeps the already-renamed `LICENSE.electron.txt`
+ * and the Chromium payload (.pak/.so/icudtl.dat/chrome-sandbox) but is MISSING
+ * the `electron` binary itself.
+ *
+ * On the next run, electron-builder sees the destination directory already
+ * populated, skips re-copying the binary it thinks is present, then tries to
+ * rename a `electron` file that no longer exists. The build dies with:
+ *
+ *   ENOENT: no such file or directory, rename
+ *   '.../release/linux-unpacked/electron' -> '.../release/linux-unpacked/Hermes'
+ *
+ * This is a hard failure with no obvious cause for the user — `hermes desktop`
+ * just prints "Desktop GUI build failed" and the only fix is to manually
+ * `rm -rf` the release directory, which a normal user has no way to know.
+ *
+ * The packaging step is not idempotent across an interrupted run, so we make
+ * it idempotent ourselves: wipe the target unpacked directory up front so
+ * electron-builder always stages into a clean tree. This is safe — the
+ * directory is a pure build artifact that electron-builder fully recreates
+ * on every pack; nothing else depends on its prior contents.
+ *
+ * Cross-platform: the same partial-state trap exists on macOS
+ * (the mac-unpacked Hermes.app bundle) and Windows (win-unpacked), so we
+ * clean whatever `appOutDir` electron-builder hands us regardless of platform.
+ *
+ * Best-effort: a cleanup failure must never mask the real build. We log and
+ * resolve rather than throw — worst case electron-builder hits the original
+ * ENOENT, which is no worse than not having this hook at all.
+ *
+ * electron-builder passes a context with:
+ *   - appOutDir:            the unpacked app directory about to be staged
+ *   - electronPlatformName: 'win32' | 'darwin' | 'linux'
