* fix(issue-5): add collision-aware pathfinding to Phaser office viewer
Agents in the Phaser office viewer previously moved in straight lines toward
zone anchors, ignoring walls, furniture, and collision geometry. This made
agents walk through rendered map obstacles.
Changes:
src/lib/office/pathfinding.ts (new):
- Shared 2D A* pathfinding module for OfficeMap surfaces
- Builds a nav grid from map objects (walls/furniture layers) and
collision polygons with configurable cell size and padding
- Diagonal corner-cutting prevention (checks both orthogonal neighbors)
- Returns empty path on failure instead of raw destination fallback
- Point-in-polygon rasterisation for collision polygon support
- Intentionally placed in src/lib/office/ for reuse across office stacks
src/features/office/phaser/systems/AgentEffectsSystem.ts:
- Computes A* waypoint paths when agent targets change
- Follows waypoints sequentially instead of linear interpolation
- Caches nav grid and invalidates on map identity change
- Agents stay put when no valid path exists (no wall clipping)
tests/unit/officePathfinding.test.ts (new):
- 12 unit tests covering grid construction, A* routing, corner-cutting
prevention, collision polygon support, blocked-start recovery, and
starter map integration
Fixes#5
* fix(test): remove unused NavGrid2D type import
