* fix(status): pick latest assistant message in single pass
Sync reconciliation can splice messages out of array order, so the
previous "filter + sort + last" pipeline could pick the wrong record
as the latest assistant message and surface a stale status.
Replace it with a single-pass scan that compares created-time (tiebreak
by id) — same selection, but resilient to non-sorted message arrays.
* refactor: use comparator + running max for latest assistant pick
Address Greptile review: collapse the dual-exit-point single-pass max
finder (separate continue + isNewer branches, repeated null checks)
into a single isLater(a, b) comparator with one running-max comparison
per iteration. Same selection rule, easier to verify.

* fix: show question content in ToolPart instead of 'Awaiting response...' after refresh
Previously, when the question tool was pending/running or completed
without parseable output, the ToolPart fell through to a generic
'Awaiting response...' message. After a page refresh or app restart,
this made questions appear empty even though the tool state still
contained the question input data.
Now the ToolPart reads question text, headers, and options from the
tool state's input field, ensuring question content persists across
refreshes regardless of QuestionCard store availability.
Fixes#879
* fix: restore QuestionCard after refresh and pause working status during active questions
Two fixes for question tool UX:
1. ChatContainer: sessionIsWorking now returns false when there are
active questions (same as it already did for permissions). This
prevents the status row from showing 'Asking question...' and
instead shows the QuestionCard.
2. sync-context: resyncDirectoryAfterReconnect now re-fetches
pending questions via listPendingQuestions(). Previously only
sessions and messages were re-fetched on SSE reconnect, so
questions asked during disconnection were lost, causing
QuestionCard to disappear after page refresh.
Refs #879
* fix: hide assistant working status while questions are pending
The assistant status hook only special-cased pending permissions, so
question tools still surfaced 'Asking question...' after refresh even
when the UI was already waiting on a QuestionCard response.
Treat pending questions like other blocking requests by clearing the
working indicator until the user answers.
Refs #879
* fix: merge question/permission stores instead of full replace on bootstrap and reconnect
The root cause of QuestionCard disappearing after refresh was a race
condition between SSE events and HTTP bootstrap. Bootstrap and reconnect
both did full replacement of state.question, wiping SSE-delivered data
that arrived between the HTTP call initiation and response arrival.
Changes:
- bootstrap.ts: question and permission stores now use merge semantics.
Only sessions present in the API response are overwritten. Sessions
absent from the response are left untouched (they may hold SSE data).
- sync-context.tsx: reconnect question resync uses the same merge pattern.
No longer clears question entries for sessions not in the API response.
- bootstrap.ts: sdk.question.list() now passes directory parameter to
scope the query correctly.
This ensures SSE-delivered question data survives the bootstrap window,
while still allowing the API response to be authoritative for sessions
it covers.

Split proxy, routes, runtime helpers, and notification emitter
into dedicated modules under packages/web/server/lib/.
* refactor: replace session/message stores with SSE-driven sync layer
Delete ~9200 lines of old architecture (useEventStream, messageStore,
sessionStore, useSessionStore, questionStore, useTodoStore, client SSE).
New sync layer: event pipeline with coalescing + 16ms flush, pure event
reducer, per-directory child stores with LRU eviction, cursor pagination,
optimistic updates, deferred timeline staging, text throttle.
Migrate all UI consumers to sync hooks (useSessionMessages,
useSessionMessageRecords, useSessionStatus, useSessionPermissions, etc).
Strip session-ui-store to UI-only state, delegate SDK ops to
session-actions with abort-if-busy, optimistic store updates, and
response merging for revert/fork/archive/delete.

abort, commands, revert, fork, and other operations returned 500.
Add routeMessage() in session-ui-store for shell mode (session.shell),
slash commands (session.command), and normal prompts. Command lookup
checks both sync child store and useCommandsStore. Handle /compact
locally via session.summarize().
Implement getContextUsage() to restore header context usage display —
reads token counts from last assistant message in sync store.

manipulation, hop-by-hop filtering, SSE block buffering.
Replace with single createProxyMiddleware() call that handles
SSE streaming, large bodies, and timeouts out of the box.
Dynamic router for OpenCode port changes after restarts.
Auth headers injected via proxyReq hook.
Keep: readiness gate, Windows session merge, API prefix detection.
* perf: targeted event draft cloning to fix streaming render cascade
Event handler was eagerly cloning all state slices on every event,
breaking Zustand selector referential equality. During streaming
(~60 events/sec), this caused every subscriber to re-render regardless
of which slice actually changed.
Now only clones fields the specific event type mutates. Also extracts
StatusRowContainer to isolate high-frequency useAssistantStatus
subscription, removes dead messageStreamStatesMap subscription from
ChatContainer, and narrows useAssistantStatus to only track last
assistant message parts.
MessageList renders: 1972 → 296 per streaming session (-85%).
* fix: null safety for sync state slices
Add defensive ?? {} guards on permission, question, session_status,
and message record access. Prevents crashes when child store state
is partially initialized during bootstrap.
* perf: dedup inflight SDK calls, extract concurrency util, delay PR tracking
Extract mapWithConcurrency to shared lib/concurrency.ts. Add in-flight
dedup for loadProviders/loadAgents to prevent concurrent duplicate SDK
calls. Delay initial PR background tracking by 5s to reduce startup
CPU burst.
* fix: header session lookup across all child stores
Session title and context panel click failed when session belonged to
a different directory than the current child store. Fall back to
getAllSyncSessions() to search all initialized stores.

## What / Why
This PR finishes the desktop refactor: the Tauri app is now a thin shell that launches the web server as a sidecar and loads the UI from `http://127.0.0.1:<port>`. All real backend logic lives in `packages/web/server/index.js`; desktop Rust keeps only native integrations (menu/dialog/notifications/updater/deep-link + window chrome).
This unblocks:
- consistent behavior across web/desktop/vscode (single backend)
- simpler desktop maintenance (no duplicated Rust backend)
- host switching between Local + remote instances in desktop
- reliable cold-start behavior on slow machines (VSCode + desktop)
## Key changes
- Desktop sidecar runtime
- build pipeline to bundle web dist + `openchamber-server` sidecar (`packages/desktop/scripts/build-sidecar.mjs`)
- robust local port selection (prefer saved/default, fallback to random; persisted in `~/.config/openchamber/settings.json`)
- improved PATH handling so the sidecar can locate `opencode` CLI (incl `~/.opencode/bin`, overrides, common bins)
- disable native right-click context menu in production builds (dev keeps it)
- Desktop instance switcher (Tauri-only)
- header button + modal to add/edit/delete remote hosts, set default, probe status/ping, switch back to Local escape hatch
- auth gate includes host switcher so you can recover when a remote host is broken/auth-required
- host list stored desktop-locally (not tied to the currently selected remote server)
- Notifications
- decision logic moved server-side; desktop notifications emitted via sidecar stdout and shown natively by Tauri
- prevent double-notifications on desktop Local origin (UI ignores SSE notification when native path is active)
- restore macOS notification sound
- Updates
- Tauri updater used only when viewing Local instance in desktop shell (avoid “remote web update” triggering desktop restart)
- Settings persistence & UX polish
- persist model favorites/recents via `/api/config/settings` (works for web + desktop; not origin-dependent)
- persist per-project sidebar collapse state in `projects[].sidebarCollapsed` via `/api/config/settings` (with debounce on toggles)
- macOS header sizing/traffic-lights offsets fixed (marketing macOS major injected from desktop; MultiRun header aligned)
- VSCode cold-start: keep retrying provider/agent loads after connection to avoid empty UI on slow machines
- misc lint/type fixes + bun.lock sync
- Desktop bootstrap / resiliency
- show onboarding screen when OpenCode CLI is missing (desktop Local origin), with retry hook to restart OpenCode after install
## Testing notes
- Desktop (macOS): switch Local <-> remote, set default host, verify auth gate recovery, native notifications (with sound), updater gated to Local
- Web: favorites/recents + per-project collapsed state persist across reload/restart
- VSCode: slow startup no longer results in missing providers/agents/models
