Skyler Lehmkuhl 33dec6f327 export: 10-bit HDR video frame path + UI (Stage B pt 2)
Wire HDR frame production end-to-end (encoder side was pt 1):
- linear_to_pq.wgsl: linear scene HDR (BT.709, white=1.0) → BT.2020 primaries →
  PQ (203-nit) or HLG OETF → gamma-encoded R'G'B'. Inverse of the nv12 decode, so
  a decode→encode round-trip is the identity.
- hdr_frame.rs (isolated module): runs that pass into an Rgba16Float target, does a
  synchronous readback (f16-decoded on CPU), then BT.2020 R'G'B'→Y'CbCr limited
  4:2:0 10-bit pack → YUV420P10LE planes. Rgba16Float avoids the 16BIT_NORM device
  feature dependency.
- video_exporter::render_frame_to_yuv10_hdr: composite + HDR encode, returning
  10-bit planes; lazily builds the pipeline.
- orchestrator: HDR uses a synchronous 1-frame-per-call path (the async RGBA
  pipeline is 8-bit only); zero-copy is skipped for HDR.
- dialog: "Dynamic range" dropdown (SDR / HDR10 PQ / HLG).

Software HEVC Main10 path; favors correctness over throughput. Compiles; runtime
verification needs a GPU + HDR-capable player.
