claude code agent 227 4c0a4eb9cc fix(ai-chat): settle detached runs on pre-stream failures + review fixes (#184) ...

CRITICAL: any failure between a successful beginRun and streamText's terminal
callbacks taking ownership (the bare awaits: user-message insert, history load,
convertToModelMessages, settings resolve; the buildSystemPrompt/forUser block;
and synchronous streamText wiring) left ai_chat_runs stuck 'running' forever
(sweepRunning only runs at startup), which then 409'd every future turn in the
chat and made the observer tab poll forever. Wrap the body of stream() after
beginRun in a safety-net try/catch that settles the run to 'error' (via
onSettled) before rethrowing, and make finalizeRun idempotent (active.delete is
the once-guard) so a settle here and a settle from a streamText callback collapse
to a single terminal write.

Also from review comment 2519:
- correct three client comments that falsely claimed /ai-chat/run is "flag-gated
  server-side and would 403" — it is owner-gated only; with the feature off the
  chat simply has no runs so the endpoint returns { run: null }
  (ai-chat-window.tsx, ai-chat-service.ts, ai-chat-query.ts).
- remove the dead UpdatableAiChatRun type (zero usages; the repo update uses an
  inline Partial<...>).
- add controller specs for POST /ai-chat/run and /ai-chat/stop (owner-gating,
  run:null when no run, run+message, stop by runId and by chatId).
- add tests: an exception after beginRun settles the run to 'error' and drops the
  in-memory entry (next turn is not 409'd); finalizeRun is idempotent.
