Erik 4be392b361 refactor(A.5 T9): _surfaceCache -> ConcurrentDictionary for off-thread mesh build ... Widens LandblockMesh.Build's surfaceCache parameter from Dictionary to IDictionary so any IDictionary implementation compiles at call sites. Switches GameWindow._surfaceCache from Dictionary to ConcurrentDictionary so T11's streaming worker can call Build off the render thread without a lock. The TryGetValue+assign lookup inside Build is not atomic, but BuildSurface is deterministic (same palCode -> same SurfaceInfo), making last-write-wins under concurrent access benign. Comment added at the pattern site. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-09 22:55:53 +02:00
