Buzz Desktop release v0.5.5

  • Frozen main: 4a2305170eef565bf1836e2859247e67c030f8af
  • Reviewed candidate: 2d03d37b05b68186b2caad9da79080032be3ac72
  • Previous desktop release: desktop-v0.5.4
  • Proposed immutable tag: desktop-v0.5.5

This PR must be squash merged only after the Desktop Release Candidate check passes. The branch must remain based directly on current main; stale base, payload drift, incomplete notes, or an unauthorized merge produce no tag.

The checked-in changelog accounts for every non-merge commit in the release range. Publication remains bound to the immutable candidate tag.

## Summary

Redesign the permanent Desktop release flow so unrelated merges to
`main` cannot invalidate an already reviewed, green release candidate.

- Tag the immutable, API-confirmed release PR head instead of its later
squash commit.
- Treat the merged PR—including an authorized owner/admin bypass—as
publication authorization, while requiring trusted check evidence that
was complete at merge time.
- Make tag creation idempotent and collision-safe: an existing tag
succeeds only at the exact candidate SHA, and create races refetch
before accepting equality.
- Replace ancestry-based previous-release discovery with a validated
metadata ledger for side-history candidate tags.
- Compute the next release from the prior frozen base to the new frozen
base, excluding only the prior release squash SHA so unrelated commits
remain in the changelog.
- Preserve schema-1 production-tag migration and reject malformed
metadata or equal/decreasing versions.
- Update operator documentation for the normal squash-merge workflow.

This is the reusable release process for `0.5.6` onward, not the retired
one-shot `0.5.5` recovery path.

### Invariants covered

- Candidate creation → unrelated `main` merge → authorized squash merge
→ immutable candidate tag.
- Trusted producer IDs and merge-time completion timestamps; DCO's
bounded post-merge exception remains isolated.
- Missing/spoofed checks, tampered candidates, ambiguous PR
associations, conflicting tags, and equal/decreasing versions fail
closed.
- Same-SHA retries succeed; different-SHA collisions fail.
- Legacy schema-1 tag-on-main migration and schema-2 side-history
accounting both preserve the correct next-release changelog.

### Related issue

N/A — follows the Desktop release failures in #4788 and #4800 and the
recovery revert in #4808.

### Testing

At clean commit `6a91fbed8147a48cf174997de0c3e4cb2fb26474`:

- `scripts/test-desktop-release-candidate.sh`
- `scripts/test-release-ref-contract.sh`

Both focused suites passed with HEAD unchanged. Princess Donut cleared
the security/provenance surface, including the hostile merge-time
timestamp cases. Mongo cleared the side-history ledger, migration,
version-order, documentation, and contract-test surface.
