* feat(chat): Chat V2 — sidebar entry + main-area page
Replace the floating drawer + FAB with a first-class workspace route
`/:slug/chat`. Sidebar gets a single `Chat` entry under Inbox with an
unread dot; session history lives inside the Chat tab via a popover
rather than leaking into the global sidebar (keeps Multica's "nouns in
the nav" semantic — Inbox / Issues / Projects are work objects, Chat is
a tool).
- Add `paths.workspace(slug).chat()` + update link-handler route set.
- New `ChatPage` view with PageHeader, history popover, centered
messages/composer column, and empty-state starter prompts.
- Delete `ChatWindow`, `ChatFab`, resize helpers, and standalone
`ChatSessionHistory` (history now embedded in the popover).
- Drop `isOpen`/`toggle`/`showHistory`/resize fields from `useChatStore`
— the page is a route now, not an overlay.
- Wire the new `/chat` route on web (App Router) and desktop
(react-router + tab-store icon mapping).

* fix(chat): align composer width with message column
The ChatPage wrapper added px-4 on top of ChatInput's own px-5, making
the composer 32px narrower than the messages column. Drop the outer
px-4 so both share the same max-w-3xl outer + px-5 inner padding
provided by ChatMessageList / ChatInput.
* fix(chat): taller default composer (~3 lines visible, 8 max)
min-h 4rem → 7rem, max-h 10rem → 15rem. Empty state previously
showed only 1 text row after pb-9 for the action bar; raise the
floor so there's visible writing room and lift the ceiling so a
longer draft can grow before scrolling kicks in.
* fix(chat): restore anchor + in-flight indicator + cold-start session restore
Three issues surfaced by review:
1. ContextAnchorButton always disabled on /:slug/chat — useRouteAnchorCandidate
only matches issue/project/inbox pathnames, so moving chat to its own route
dropped 'bring the page I was on into the conversation'. Track the last
anchor-eligible location globally (new useAnchorTracker mounted in AppSidebar
+ lastAnchorLocation on useChatStore) and substitute it when on /chat.
2. No global 'Multica is working' cue after ChatFab deletion. Subscribe the
sidebar Chat entry to pendingChatTasksOptions and swap the unread dot for a
spinner while any chat task is in flight.
3. ChatPage restore effect latched didRestoreRef before the sessions query
resolved, so cold-start direct nav to /chat landed on the empty state even
when the server had an active session. Wait for isSuccess before locking
the ref.
* fix(chat): clear lastAnchorLocation on workspace rehydration
The pathname captured in workspace A would otherwise be reused against
workspace B's wsId, triggering a cross-workspace issue/project fetch
and silently leaking anchor context into chat messages.

* refactor(views): extract IssueChip shared primitive from mention card
IssueMention (in editor NodeView) and IssueMentionCard shared 95% of their
markup — StatusIcon + identifier + title inside a bordered chip. They drifted
into two parallel implementations so changes had to be made in two places.
Extract the presentational chip into IssueChip. The navigable variants
(IssueMentionCard, the editor NodeView) become thin shells that layer
routing + cmd/shift behaviour onto the shared chip.

* feat(chat): add focus mode to share current page as context
Adds a Focus button next to the chat submit. When on, the chat auto-attaches
whatever the user is viewing (issue, project, or inbox-selected issue) as a
context prefix on outgoing messages, so the agent knows what "this" refers
to without the user pasting ids.
The attached object is derived from the route + react-query cache on every
render — no separate copy in state. Only the boolean focusMode is persisted
(global to the user, not per-workspace), matching the "my preference"
mental model.
The button has three visual states driven by two dimensions (focusMode +
whether the current route resolves to an anchorable object):
- off: ghost + muted, click turns on
- on + anchor: secondary (bright), click turns off
- on + none: disabled (nothing to attach here)
The derived anchor renders above the input as a chip — IssueChip for issues,
a new ProjectChip for projects — wrapped in AppLink so the visual target
matches the clickable target (mirrors IssueMentionCard's hover + navigation).
Prefix format reuses the editor's mention markdown:
Context: [MUL-1](mention://issue/<uuid>) — "Fix login bug"
Context: Project "Authentication"
so the agent sees an identical token whether the user @-mentioned inline or
focus-mode attached. Backend is untouched.

State management
- Pending task / live timeline are now Query-cache single source;
Zustand mirror removed (fixes duplicate assistant render caused by
the invalidate→refetch race window)
- WS subscriptions moved from ChatWindow to global useRealtimeSync so
pending state survives minimize and refresh
- New GET /chat/sessions/:id/pending-task to recover live state on mount
- Drafts persisted per-session (was per-workspace)
Unread tracking
- Migration 040: chat_session.unread_since (event-driven; old chats
stay clean — no mass backfill)
- POST /chat/sessions/:id/read clears unread; broadcasts
chat:session_read so other devices sync
- New GET /chat/pending-tasks aggregate for the FAB
- ChatFab: brand-color impulse animation while running, brand-dot
badge of unread session count
- ChatWindow auto-marks read when user is viewing the session
Header redesign
- Two independent dropdowns: agent (avatar + name + My/Others
grouping) at the input bottom-left; session (title + agent avatar)
in the header
- ⊕ new-chat button replaces the old + and history buttons
- Session dropdown lists all sessions across agents with avatars
- Empty state: 3 clickable starter prompts that send immediately
- Mention link renderer falls through to default span on null —
fixes @member/@agent/@all silently disappearing app-wide
- User messages render through Markdown
- Enter submits in chat input only (with IME guard + codeBlock skip);
bubble menu hidden in chat
Misc
- Partial index on agent_task_queue for fast pending-task lookup
- 2 new storage keys added to clearWorkspaceStorage
- useMarkChatSessionRead has onError rollback
- chat.* namespace logs across store, mutations, components, realtime

- Refactor store to persist raw user intent (chatWidth/chatHeight/isExpanded) with no clamp logic
- Add ResizeObserver-based resize hook for dynamic container tracking
- Add drag-to-resize handles (left, top, corner) with pointer capture
- Expand/Restore button uses visual state (isAtMax) not internal flag
- Open/close animation (scale + opacity from bottom-right)
- Resize animation on button click, instant on drag (isDragging gate)
- Move ChatWindow inside content area (absolute, not fixed)
- Add input draft persistence, remove agent prop from message list

Move chat queries, mutations, and store from apps/web/core/chat/ and
apps/web/features/chat/store.ts to packages/core/chat/. Refactor store
to use createChatStore({ storage }) factory pattern (mirrors auth store)
so it works in both web (localStorage) and desktop (Electron) without
direct browser API access. Register chat store in CoreProvider.initCore.
