User explicitly redirected the next-phase track: no M2 (kill-a-drudge), stay
on indoor walking issues, collision, physics, and dungeons. Update the
pickup prompt to reflect this:
- Drop M2 from the candidate list entirely.
- Add #83 (walking up stairs) as the recommended next phase — pure
indoor/physics, unblocks both multi-floor cottages AND dungeons.
- Add a "dungeon stress test" candidate (Path B) — verify Phase 2's
portal traversal works on multi-cell indoor spaces.
- Move indoor lighting from "recommended" to Path E with a note that it
depends on stairs (#83) landing first to be testable.
- Update the helper section with concrete file pointers per path.
