Vendored DS4 Metal boundary

The Metal bridge and GPU declarations track the DS4 boundary audited at commit ec7642cdd9ec81d01ad4b1fd8f8a3d1511533748 (2026-08-31):

  • ds4_metal.m
  • ds4_gpu.h

The matching Metal kernels, including glm53_*.metal, live in the repository-level metal/ directory. The other headers remain DS4Server-owned interfaces and are not copies of DS4 application code. DS4Server builds and bundles this local snapshot; it does not read a sibling DS4 checkout. Rust owns the model, graph, session, sampling, and lifecycle. Objective-C remains only at the platform Metal boundary.
