Skyler Lehmkuhl ba897eaea2 gpu-video-encoder: complete zero-copy H.264 encode pipeline
Build the full end-to-end zero-copy encoder, validated on Intel/VAAPI:

- render_nv12: fragment-shader RGBA->NV12 that renders luma/chroma into
  the imported R8/RG8 plane render targets (compute storage can't write
  the DMA-BUF-backed planes; render attachments can).
- dmabuf: import_raw imports an NV12 DMA-BUF by explicit layout; the two
  plane images + shared memory are now destroyed by wgpu via texture_from_raw
  drop callbacks (Arc MemoryGuard frees the memory once both images are
  gone, in wgpu's wait-idle'd deferred pass) -- fixes the teardown segfault.
- encoder::ZeroCopyEncoder: renders an RGBA texture straight into a pooled
  VAAPI surface (imports cached by VASurface id) and encodes with h264_vaapi.
  encode_rgba + finish; the caller renders on device().

Tests: real-frame render into the surface matches the CPU NV12 reference,
and a 30-frame encode produces valid H.264 (ffprobe-verified) with clean
teardown. Not yet wired into the editor.
