ci(release): stop running the PR-quality gate on tag releases

Release is gated on the tag only. `bun run verify` runs on PRs and locally,
not at release time, so a failing quality gate no longer blocks publishing.

- release-desktop.yml: remove the quality-preflight job and its `needs`.
- release-workflow.test.ts: assert the release workflow does NOT run verify.
