jpmschweitzerandClaude Opus 4.6 f87bd2b0e5 feat(simulation): add entity-entity collision 
validate_movement now checks both terrain walkability AND tile
occupancy. Builds a spatial index of occupied tiles from stationary
entities, then resolves movers in order — first valid claim wins.

Same spatial pattern needed for D-026 simulation tiers (30-80 active
NPCs) and future pathfinding occupied-tile awareness.

jpmschweitzerandClaude Opus 4.6 bef4383196 feat(simulation): add 8-directional movement 
Add diagonal PlayerAction variants (MoveNortheast, MoveNorthwest,
MoveSoutheast, MoveSouthwest) and TilePosition::all_neighbors()
returning all 8 surrounding tiles. Genre-expected for immersive sim.

Establishes the movement pattern before pathfinding is built on top.

jpmschweitzerandClaude Opus 4.6 862ab9099f feat(simulation): add tile collision system (#236) 
TilePosition component with discrete grid coordinates, flat-storage
WalkabilityMap resource with O(1) can_move_to() lookup, MoveIntent
component and validate_movement system. Movement validated against
walkability map each tick, blocking all NPC and player movement
through unwalkable tiles. 11 unit tests + 1 integration test.

jpmschweitzerandClaude Opus 4.6 4ed15c1a38 feat(simulation): add LocalBridge IPC over Unix socket (#78) 
Length-prefixed MessagePack framing (4-byte BE length + payload),
LocalBridge struct implementing SimBridge trait over Unix domain
sockets, BridgeResource wrapper for ECS integration. Adds Io
error variant to BridgeError. Two integration tests verify
snapshot and input round-trips over real sockets.

jpmschweitzerandClaude Opus 4.6 f67caf1986 feat(server): initialize Rust/bevy_ecs simulation server 
Server boilerplate epic (276) complete. Establishes the Rust simulation
server foundation per D-020 (subprocess/IPC architecture).

Structure:
- bevy_ecs 0.18 + bevy_app 0.18, MessagePack serialization (rmp-serde)
- SimulationPlugin with deterministic resources: SimulationTime (D-031),
  SimRng (D-030), InputQueue (D-010)
- Core IPC types: ObserverSnapshot, PlayerInput, SimBridge trait (D-020)
- CauseChain production component for provenance tracking (D-030)
- SimulationTier types with LRU eviction support (D-026)
- NPC 10-axis model components (D-024)
- 15 tests: inline unit tests + integration smoke/serialization tests
- make ci-server passes (clippy, fmt, build, test)
