refactor(desktop): tighten right-rail tab close API

Promote closeRightRailTab/closeActiveRightRailTab as the single
public entry point. Drops the activeTabRef + handleCloseDocument
indirection in ChatPreviewRail, the unused $rightRailHasContent
atom, and the legacy dismissFilePreviewTarget alias. -70 LOC.

+# Dependabot configuration for hermes-agent.
+#
+# Deliberately scoped to github-actions only.
+#
+# We do NOT enable Dependabot for pip / npm / any source-dependency ecosystem
+# because we pin source dependencies exactly (uv.lock, package-lock.json) as
+# part of our supply-chain posture. Automatic version-bump PRs against those
+# pins would undermine the strategy — pins are moved deliberately, after
+# review, not on a schedule.
+#
+# github-actions is the exception: action pins (we use full commit SHAs per
+# supply-chain policy) must be updated when upstream actions publish
+# patches — usually themselves security fixes. Dependabot opens a PR with
+# the new SHA and release notes; we review and merge like any other PR.
+#
+# Security-update PRs for source dependencies (opened ONLY when a CVE is
+# published affecting a currently-pinned version) are enabled separately
+# via the repo's Dependabot security updates setting
+# (Settings → Code security → Dependabot → Dependabot security updates).
+# Those are CVE-only, not schedule-driven, and do not conflict with our
+# pinning strategy — they fire when a pinned version becomes known-bad,
+# which is exactly when we want to move the pin.

+## TypeScript Style
+
+Applies to TypeScript across Hermes: desktop, TUI, website, and future TS packages.
+
+- Prefer small nanostores over component state when state is shared, reused, or read by distant UI.
+- Let each feature own its atoms. Chat state belongs near chat, shell state near shell, shared state in `src/store`.
+- Components that render from an atom should use `useStore`. Non-rendering actions should read with `$atom.get()`.
+- Do not pass state through three components when the leaf can subscribe to the atom.
+- Keep persistence beside the atom that owns it.
+- Keep route roots thin. They compose routes and shell; they should not become controllers.
+- No monolithic hooks. A hook should own one narrow job.
+- Prefer colocated action modules over hidden god hooks.
+- If a callback is pure side effect, use the terse void form:
+  `onState={st => void setGatewayState(st)}`.
+- Async UI handlers should make intent explicit:
+  `onClick={() => void save()}`.
+- Prefer interfaces for public props and shared object shapes. Avoid `type X = { ... }` for object props.
+- Extend React primitives for props: `React.ComponentProps<'button'>`, `React.ComponentProps<typeof Dialog>`, `Omit<...>`, `Pick<...>`.
+- Table-driven beats condition ladders when mapping ids, routes, or views.
+- `src/app` owns routes, pages, and page-specific components.
+- `src/store` owns shared atoms.
+- `src/lib` owns shared pure helpers.

+`"messaging"`); `_HERMES_CORE_TOOLS` is the default bundle most
+platforms inherit from.
+
+Current toolset keys: `browser`, `clarify`, `code_execution`, `cronjob`,

+`feishu_drive`, `file`, `homeassistant`, `image_gen`, `kanban`, `memory`,

+
+## Delegation (`delegate_task`)
+
+`tools/delegate_tool.py` spawns a subagent with an isolated
+context + terminal session. Synchronous: the parent waits for the
+child's summary before continuing its own loop — if the parent is
+interrupted, the child is cancelled.
+
+Two shapes:
+
+- **Single:** pass `goal` (+ optional `context`, `toolsets`).
+- **Batch (parallel):** pass `tasks: [...]` — each gets its own subagent
+  running concurrently. Concurrency is capped by
+  `delegation.max_concurrent_children` (default 3).
+
+Roles:
+
+- `role="leaf"` (default) — focused worker. Cannot call `delegate_task`,
+  `clarify`, `memory`, `send_message`, `execute_code`.
+- `role="orchestrator"` — retains `delegate_task` so it can spawn its
+  own workers. Gated by `delegation.orchestrator_enabled` (default true)
+  and bounded by `delegation.max_spawn_depth` (default 2).
+
+Key config knobs (under `delegation:` in `config.yaml`):
+`max_concurrent_children`, `max_spawn_depth`, `child_timeout_seconds`,
+`orchestrator_enabled`, `subagent_auto_approve`, `inherit_mcp_toolsets`,
+`max_iterations`.
+
+Synchronicity rule: delegate_task is **not** durable. For long-running
+work that must outlive the current turn, use `cronjob` or
+`terminal(background=True, notify_on_complete=True)` instead.
+
+---
+
+## Curator (skill lifecycle)
+
+Background skill-maintenance system that tracks usage on agent-created
+skills and auto-archives stale ones. Users never lose skills; archives
+go to `~/.hermes/skills/.archive/` and are restorable.
+
+- **Core:** `agent/curator.py` (review loop, auto-transitions, LLM review
+  prompt) + `agent/curator_backup.py` (pre-run tar.gz snapshots).
+- **CLI:** `hermes_cli/curator.py` wires `hermes curator <verb>` where
+  verbs are: `status`, `run`, `pause`, `resume`, `pin`, `unpin`,
+  `archive`, `restore`, `prune`, `backup`, `rollback`.
+- **Telemetry:** `tools/skill_usage.py` owns the sidecar
+  `~/.hermes/skills/.usage.json` — per-skill `use_count`, `view_count`,
+  `patch_count`, `last_activity_at`, `state` (active / stale /
+  archived), `pinned`.
+
+Invariants:
+- Curator only touches skills with `created_by: "agent"` provenance —
+  bundled + hub-installed skills are off-limits.
+- Never deletes; max destructive action is archive.
+- Pinned skills are exempt from every auto-transition and from the
+  LLM review pass.
+- `skill_manage(action="delete")` refuses pinned skills; patch/edit/
+  write_file/remove_file go through so the agent can keep improving
+  pinned skills.
+
+Config section (`curator:` in `config.yaml`):
+`enabled`, `interval_hours`, `min_idle_hours`, `stale_after_days`,
+`archive_after_days`, `backup.*`.

+Full user-facing docs: `website/docs/user-guide/features/curator.md`.

+
+## Cron (scheduled jobs)
+
+`cron/jobs.py` (job store) + `cron/scheduler.py` (tick loop). Agents
+schedule jobs via the `cronjob` tool; users via `hermes cron <verb>`
+(`list`, `add`, `edit`, `pause`, `resume`, `run`, `remove`) or the
+`/cron` slash command.
+
+Supported schedule formats:
+- Duration: `"30m"`, `"2h"`, `"1d"`
+- "every" phrase: `"every 2h"`, `"every monday 9am"`
+- 5-field cron expression: `"0 9 * * *"`
+- ISO timestamp (one-shot): `"2026-06-01T09:00:00Z"`
+
+Per-job fields include `skills` (load specific skills), `model` /
+`provider` overrides, `script` (pre-run data-collection script whose
+stdout is injected into the prompt; `no_agent=True` turns the script
+into the entire job), `context_from` (chain job A's last output into
+job B's prompt), `workdir` (run in a specific directory with its
+`AGENTS.md`/`CLAUDE.md` loaded), and multi-platform delivery.
+
+Hardening invariants:
+- **3-minute hard interrupt** on cron sessions — runaway agent loops
+  cannot monopolize the scheduler.
+- Catchup window: half the job's period, clamped to 120s–2h.
+- Grace window: 120s for one-shot jobs whose fire time was missed.
+- File lock at `~/.hermes/cron/.tick.lock` prevents duplicate ticks
+  across processes.
+- Cron sessions pass `skip_memory=True` by default; memory providers
+  intentionally do not run during cron.
+
+Cron deliveries are **not** mirrored into the target gateway session —
+they land in their own cron session with a header/footer frame so the
+main conversation's message-role alternation stays intact.
+
+---
+
+## Kanban (multi-agent work queue)
+
+Durable SQLite-backed board that lets multiple profiles / workers
+collaborate on shared tasks. Users drive it via `hermes kanban <verb>`;
+workers spawned by the dispatcher drive it via a dedicated `kanban_*`
+toolset so their schema footprint is zero when they're not inside a
+kanban task.
+
+- **CLI:** `hermes_cli/kanban.py` wires `hermes kanban` with verbs
+  `init`, `create`, `list` (alias `ls`), `show`, `assign`, `link`,
+  `unlink`, `comment`, `complete`, `block`, `unblock`, `archive`,
+  `tail`, plus less-commonly-used `watch`, `stats`, `runs`, `log`,
+  `assignees`, `heartbeat`, `notify-*`, `dispatch`, `daemon`, `gc`.
+- **Worker toolset:** `tools/kanban_tools.py` exposes `kanban_show`,
+  `kanban_complete`, `kanban_block`, `kanban_heartbeat`, `kanban_comment`,
+  `kanban_create`, `kanban_link` — gated by `HERMES_KANBAN_TASK` so
+  the schema only appears for processes actually running as a worker.
+- **Dispatcher:** long-lived loop that (default every 60s) reclaims
+  stale claims, promotes ready tasks, atomically claims, and spawns
+  assigned profiles. Runs **inside the gateway** by default via
+  `kanban.dispatch_in_gateway: true`.
+- **Plugin assets:** `plugins/kanban/dashboard/` (web UI) +
+  `plugins/kanban/systemd/` (`hermes-kanban-dispatcher.service` for
+  standalone dispatcher deployment).
+
+Isolation model:
+- **Board** is the hard boundary — workers are spawned with
+  `HERMES_KANBAN_BOARD` pinned in their env so they can't see other
+  boards.
+- **Tenant** is a soft namespace *within* a board — one specialist
+  fleet can serve multiple businesses with workspace-path + memory-key
+  isolation.
+- After ~5 consecutive spawn failures on the same task the dispatcher
+  auto-blocks it to prevent spin loops.

+"""Lightweight internationalization (i18n) for Hermes static user-facing messages.
+
+Scope (thin slice, by design): only the highest-impact static strings shown
+to the user by Hermes itself -- approval prompts, a handful of gateway slash
+command replies, restart-drain notices.  Agent-generated output, log lines,
+error tracebacks, tool outputs, and slash-command descriptions all stay in
+English.
+
+Catalog files live under ``locales/<lang>.yaml`` at the repo root.  Each
+catalog is a flat dict keyed by dotted paths (e.g. ``approval.choose`` or
+``gateway.approval_expired``).  Missing keys fall back to English; if English
+is missing too, the key path itself is returned so a broken catalog never
+crashes the agent.
+
+Usage::
+
+    from agent.i18n import t
+    print(t("approval.choose_long"))                       # current lang
+    print(t("gateway.draining", count=3))                  # {count} formatted
+    print(t("approval.choose_long", lang="zh"))            # explicit override
+
+Language resolution order:
+    1. Explicit ``lang=`` argument passed to :func:`t`
+    2. ``HERMES_LANGUAGE`` environment variable (for tests / quick override)
+    3. ``display.language`` from config.yaml
+    4. ``"en"`` (baseline)

+"""Stateful scrubber for reasoning/thinking blocks in streamed assistant text.
+
+``run_agent._strip_think_blocks`` is regex-based and correct for a complete
+string, but when it runs *per-delta* in ``_fire_stream_delta`` it destroys
+the state that downstream consumers (CLI ``_stream_delta``, gateway
+``GatewayStreamConsumer._filter_and_accumulate``) rely on.
+
+Concretely, when MiniMax-M2.7 streams
+
+    delta1 = "<think>"
+    delta2 = "Let me check their config"
+    delta3 = "</think>"
+
+the per-delta regex erases delta1 entirely (case 2: unterminated-open at
+boundary matches ``^<think>...``), so the downstream state machine never
+sees the open tag, treats delta2 as regular content, and leaks reasoning
+to the user.  Consumers that don't run their own state machine (ACP,
+api_server, TTS) never had any defence at all — they just emitted
+whatever survived the upstream regex.
+
+This module centralises the tag-suppression state machine at the
+upstream layer so every stream_delta_callback sees text that has
+already had reasoning blocks removed.  Partial tags at delta
+boundaries are held back until the next delta resolves them, and
+end-of-stream flushing surfaces any held-back prose that turned out
+not to be a real tag.
+
+Usage::
+
+    scrubber = StreamingThinkScrubber()
+    for delta in stream:
+        visible = scrubber.feed(delta)
+        if visible:
+            emit(visible)
+    tail = scrubber.flush()  # at end of stream
+    if tail:
+        emit(tail)
+
+The scrubber is re-entrant per agent instance.  Call ``reset()`` at
+the top of each new turn so a hung block from an interrupted prior
+stream cannot taint the next turn's output.
+
+Tag variants handled (case-insensitive):
+  ``<think>``, ``<thinking>``, ``<reasoning>``, ``<thought>``,
+  ``<REASONING_SCRATCHPAD>``.
+
+Block-boundary rule for opens: an opening tag is only treated as a
+reasoning-block opener when it appears at the start of the stream,
+after a newline (optionally followed by whitespace), or when only
+whitespace has been emitted on the current line.  This prevents prose
+that *mentions* the tag name (e.g. ``"use <think> tags here"``) from
+being incorrectly suppressed.  Closed pairs (``<think>X</think>``) are
+always suppressed regardless of boundary; a closed pair is an
+intentional, bounded construct.
