docs(roadmap): mark Phase B.1 + B.3 as shipped

Browse source 
B.1 (ack pump) was already shipped as Phase 4.9 — updated the
roadmap entry to reflect this. B.3 (physics collision engine)
shipped with 4 commits (TerrainSurface, CellSurface, PhysicsEngine,
GameWindow integration). 243 tests green.

Next: B.2 (player movement mode — wire WASD to collision engine
+ outbound server message).

- **B.1 — Outbound ack pump.** Background timer that sends sequence acks every ~250ms. Without this the server drops idle clients after ~30s regardless of any other activity. - **✓ SHIPPED — B.1 — Outbound ack pump.** Shipped as Phase 4.9 — per-packet ACK_SEQUENCE, not periodic. Server no longer drops idle clients.
- **B.2 — `PlayerAutonomousMove` outbound.** Wire WASD + camera state (or a dedicated player-controlled movement mode) to an outbound movement message so the server's view of the character matches ours. - **B.2 — `PlayerAutonomousMove` outbound.** Wire WASD + camera state (toggle between fly mode and player mode) to an outbound movement message so the server's view of the character matches ours. Requires B.3.
- **B.3 — Collision against terrain.** Required for the server to accept moves at all — ACE rejects client positions that are inside geometry or in disallowed Z ranges. Minimum viable: sample the terrain heightmap beneath the player and clamp Z. Proper: walk the `CellBSP` / `PhysicsBSP` we already parse. - **✓ SHIPPED — B.3 — Physics collision engine.** TerrainSurface (heightmap bilinear Z), CellSurface (indoor floor polygon projection via barycentric interpolation), PhysicsEngine (top-level resolver with step-height enforcement, outdoor↔indoor cell transitions, gravity reporting).
