Danny Avila 5d6b0a5c9b 🛠️ refactor: address comprehensive review (round 3) — stale-cache MAJOR + 3 minors
Comprehensive review on PR #12957 caught a P1 follow-on bug from the
prior `invalidateQueries` fix, plus 3 maintainability findings.

MAJOR: stale React Query cache not actually fixed by `invalidateQueries`
  The previous fix called `invalidateQueries` to flush stale cached
  preview data on cross-turn filename reuse. But `useFilePreview` had
  `refetchOnMount: false`, which made the new observer read the
  stale-marked 'ready' data without refetching. The polling
  `refetchInterval` then evaluated against stale 'ready' → returned
  `false` → polling never started → user stuck on stale content.

  Fix (belt-and-suspenders):
    a) `useAttachmentHandler` switched to `removeQueries` — drops the
       cache entry entirely so the next mount has nothing to read and
       must fetch.
    b) `useFilePreview` no longer sets `refetchOnMount: false`, so the
       React Query default (`true`) kicks in — second line of defense
       if any future codepath observes stale data before the handler
       has a chance to evict.

MINOR: `finalizePreview` JSDoc missing `previewRevision` param
  Added with explanation of the conditional update guard.

MINOR: asymmetric stream-writable guard between SSE protocols
  Chat-completions delegated the gate to `writeAttachmentUpdate`;
  Open Responses inlined `!res.writableEnded && res.headersSent`.
  Extracted `isStreamWritable(res, streamId)` predicate; both paths
  + `writeAttachmentUpdate` now share the single source of truth.

NIT: `(data as Partial<TFile>).file_id` cast repeated 4 times
  Extracted to a `fileId` local at the top of the handler.

Tests: existing 9 invalidate-tests rewritten as remove-tests; +1 new
lock-in test asserts removeQueries is called and invalidateQueries
is NOT (regression guard against round-3 finding). 332 backend pass,
532 frontend pass, lint clean.

Skipped findings (deferred / acceptable):
- MINOR: post-submission pending state has no auto-recovery — the
  `isAnySubmitting` polling gate was the user's explicit design;
  LLM context surfaces failed/pending so the model can volunteer.
  Worth a follow-up if real users hit it.
- NIT: double DB query per preview poll — reviewer marked acceptable;
  changing `fileAccess` middleware is out of scope.
