Skyler Lehmkuhl bb3369b709 export: GPU-resident decode for software + HDR export (Stage 3c-export pt 1)
The software and HDR export paths already composite on the shared device (the
eframe device, via render_next_video_frame), so they can consume the same
hardware-decoded NV12 GPU frames the preview uses — no CPU download/upload:

- ExportGpuResources gains the Nv12BlitPipeline; the export compositor's Video arm
  branches on inst.gpu (NV12 blit, mirroring stage.rs) vs the RGBA upload path.
- render_frame_to_gpu_rgba takes a hardware_ok flag: true for the software video +
  image export (shared device), false for the zero-copy path (own device, must
  download). render_frame_to_yuv10_hdr sets it true.

Drops the 4K software/HDR-export decode wall (HW decode + GPU composite, no
per-frame RGBA upload). The common Linux H.264 zero-copy path is unchanged
(separate device) — that's pt 2. Falls back to software when no shared device /
importer (flag is harmless then: get_frame returns CPU anyway). Compiles.
