Adds Playwright e2e coverage for five high-value workflows, each driven
through semantic locators with API-based setup:
- comment on and close an issue
- publish a release
- star and watch a repository
- create a pull request from the compare page
- fork a repository
Also passes `autoInit: false` in existing tests that only exercise
DB-backed units (issues, reactions, milestones, projects, events),
skipping an unused initial commit to speed up their setup and reduce
parallel git contention.
