Brooklyn Nicholson 891c9a6823 fix(desktop): close eager-upload races flagged in review
Two races in the drop-time eager upload:

- Resurrected chip: the success path used addComposerAttachment, which
  re-appends when the id is gone, so a file removed mid-upload reappeared once
  the upload resolved. Add updateComposerAttachment (update-only; no-op when the
  chip was removed) and use it on both the eager success path and submit-time
  sync.
- Duplicate upload: submit-time sync didn't join an eager upload still in
  flight, so drop-then-Enter could fire file.attach twice and leave a duplicate
  under .hermes/desktop-attachments/. Track in-flight eager uploads by id and
  await the pending one before deciding to re-upload, reusing its gateway ref.

Tests: composer-store no-resurrect unit tests + a join-on-submit integration
test asserting a single file.attach.
