feat(work): auto-tick epic story bullets when a story finishes

- Add tickStoryBulletInEpic(workRoot, epic, story) helper that finds
  the bullet in the parent epic's `## Stories` section linking to the
  given story folder and flips `- [ ]` to `- [x]`. Idempotent.
- applyApprovedState now ticks the parent epic bullet whenever a
  story flips to status: done (alongside the existing per-task tick
  and epic-status flip). Epic file gets staged on either ticked-or-
  flipped, not just flipped.
- Backfill all 3 existing epics: 21 bullets ticked to match their
  already-done story statuses (binder-wrap-helper x3, library-
  evaluation-policy x9, ci-security-and-supply-chain x9).
