Jiayuan Zhang 35aca57939 feat(chat): Chat V2 — sidebar entry + main-area page (#1580)
* 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).

Addresses MUL-1322.

* 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.
