Optimize TileMap: replace HashMap with AHashMap, pack tile data
...
- Replace std HashMap (SipHash) with ahash::AHashMap for fast non-crypto hashing
- Pack tile data from tuples to structs: FloorTileData (~35 bytes) and FixtureTileData (~18 bytes)
- FloorTileData: pack 3 bools into single flags byte, use u8 for id/weight
- FixtureTileData: pack 2 bools into single flags byte
- Update all accessors: is_standable_tile, visibility, terrain generation, forestry
- Preparation for async pathfinding (Arc wrapping to come in follow-up)
Memory reduction: ~54% for floor tiles (76→35 bytes), ~62% for fixtures (48→18 bytes)
Hash performance: AHashMap uses fxhash, faster than SipHash for game data

Implement tiered pathfinding with thread-local scratchpads
...
- TIER0 (<10 tiles): Vec-based linear search, zero hash overhead
- TIER1 (10-30 tiles): FxHashMap scratchpad with memory reuse
- TIER2 (30-100 tiles): AHashMap scratchpad for better collision resistance
- TIER3 (>100 tiles): Chunk waypoint decomposition
- Added benchmarking infrastructure with F8 report trigger
- Added async infrastructure: PendingPath, CompletedPaths resources
- Lowered MAX_NODES to 5000 to prevent runaway searches
Benchmarks show P50 improved 13%, max improved 53%

Refactor visibility system to use component-based approach
...
- Introduce VisibleGameEntity component for entities needing visibility logic
- Move Z-index based visibility calculations to dedicated system
- Update both citizens and logs to use new visibility system
- Remove duplicated visibility logic from citizen movement system
- Add compute_visibility_of_game_entities system to Update phase
This improves modularity by separating visibility concerns from movement systems.
