ci(quality): shift heavy validations to the PR→release fast-path (release-acceleration) (#4857)

* feat(quality): add check:test-runner-api gate (vitest-only dirs must use vitest API)

* feat(release): reusable CHANGELOG i18n-mirror sync script

* chore(ops): add prune-stale-worktrees.sh (dry-run by default)

* ci(quality): run test-runner-api + docs-all + vitest + full unit suite on PR->release fast-path
