Major refactor of graphics pipeline keying, shader cache, and resource allocation. Replaced most Allocator usage with AllocationHandle, modernized logger usage, and unified pipeline state keys. Updated MeshUtility to use AllocationHandle.FreeList. Added new shader pipeline architecture docs and improved error handling throughout. BREAKING CHANGE: Pipeline keying and resource allocation APIs have changed.
