- Add buildFsAtSubStart so dev "Retry step" resets the current sub while keeping earlier subs complete; quiz screen clears the selected answer.
- Stop adding hinted files' parent folders to click hints (avoids wrongly highlighting Downloads when already inside it).
- Extend Playwright: localStorage reset, full playthrough through quiz, and a retry-step regression test. Add Vitest for buildFsAtSubStart.
