Summary

Core physics layer management for manipulation operations (engine-agnostic). Handles collision layer enabling/disabling during manipulation without engine dependencies.

Responsibilities:

Track physics layer state changes
Disable collision layers during manipulation
Restore original physics layer state
Provide physics layer validation
