fix(ai-chat): open chat window before resolving the bound chat (#191)

Address PR #209 review.

- use-open-ai-chat.ts: call setWindowOpen(true) before awaiting
  getBoundChat so the header button feels instant on slow connections;
  the chat switch (setActiveChatId/setDraft/setSelectedRoleId) is applied
  after the round-trip resolves. Also drop the redundant no-op
  setWindowOpen(true) in the already-open branch (bare early return).
- CHANGELOG.md: document the header AI-chat button auto-opening the
  latest chat bound to the current document under [Unreleased]/Added.

-### Added

-- **Interrupt the AI agent and send a queued message now.** A queued AI-chat
-  message gains a "send now" action that interrupts the streaming turn and
-  immediately sends that message, keeping the agent's partial output. The
-  follow-up turn is tagged as an interrupt so the model is told its previous
-  answer was cut off and builds on it instead of restarting; the rest of the
-  queue still flushes normally afterward. (#198)

-  permanent first. The deadline is frozen at creation time, so later changes to

-- **Generate a page title from its content.** A "sparkles" button in the page

-  title via the workspace AI provider (`POST /ai-chat/generate-page-title`), and
-  applies it through the existing `/pages/update` route — reflecting it in the
-  title field and broadcasting to other clients. Gated by the `settings.ai.generative`

+- **AI chat: header button auto-opens the chat bound to the current document.**
+  Clicking the AI-chat button in the header while viewing a page now reopens the
+  latest chat tied to that document instead of whatever chat was last active,
+  reusing the existing `ai_chats.page_id` provenance (no migration). The newest
+  chat you created on the page wins; with no bound chat — or off a page, or if
+  the lookup fails — it falls soft to a fresh chat and keeps the current
+  selection otherwise. (#191)
 
 ### Changed
 
-- **AI chat now feeds the model the full stored transcript.** The per-turn model
-  conversation was rebuilt from a sliding window of the 50 most recent stored
-  rows, which silently dropped the beginning of any longer chat. It is now
-  rebuilt from the complete non-deleted transcript in chronological order, so
-  the model sees every turn (a 5000-row backstop guards process memory — a
-  safety net far above any realistic chat, not a conversational limit). On a
-  very long chat this can eventually reach the model's context window; the
-  client already surfaces that as "start a new chat". (#202)
-
 - **AI chat default provider is now `openai-compatible` (reasoning surfaced).**
   For the `openai` driver the chat provider defaults to the openai-compatible
   implementation, so a workspace pointing at z.ai/GLM/DeepSeek now streams the
