Adds CachedBatch, EntityCacheEntry, and EntityClassificationCache with just TryGet (returns false on empty). The skeleton compiles and the first test (TryGet_EmptyCache_ReturnsFalse) passes. Subsequent tasks add Populate, InvalidateEntity, InvalidateLandblock, and the dispatcher integration. Per spec design Section 6.1. Note: CachedBatch / EntityCacheEntry / EntityClassificationCache are internal (not public as the plan snippet showed). Their members transitively reference the internal GroupKey type, so promoting them to public produces CS0051 inconsistent-accessibility errors. The cache is dispatcher-internal coordination state anyway, and the AcDream.App csproj already exposes internals to AcDream.Core.Tests via InternalsVisibleTo, so the test sees everything it needs.
