docs: M1.5 "Indoor world feels right" LANDED 2026-07-10 — advance to M2

User-gated the full dungeon round-trip (enter via portal -> navigate rooms ->
exit to the outdoor world), completing the #138 acceptance. Both M1.5 demo
halves are now confirmed: building/cellar (prior sessions) + full dungeon
round-trip (2026-07-10). Milestone-crossing artifacts per the milestones-doc
discipline:

- Pinned M1.5 landing writeup + flipped header to ✅ LANDED; caveats explicit
  (#145-residual far-town teleport-OUT + #116 slide-response carried as
  post-M1.5 follow-ups, NOT blockers).
- Freeze list applied: all M1.5 phases (indoor render Option A, A6/A6.P4
  physics, A7 lighting, full Phase G.3 dungeon support) now frozen per rule 2.
- M2 "Kill a drudge" flipped to ACTIVE; first ports = CombatMath.ComputeDamage
  (F.3) + inventory panel (F.2) + combat anim (L.1c).
- CLAUDE.md "currently working toward" advanced to M2.
- #138 closed (user gate).

No demo video (per the user's standing preference).
