feat(host): native AMF SDK encoder for Windows AMD — drop libavcodec
Direct-SDK AMF encoder (encode/windows/amf.rs), the AMD analogue of the
direct-NVENC path, replacing the libavcodec *_amf dispatch. C-vtable FFI
pinned to AMF headers v1.4.36, runtime-loaded from the driver's amfrt64.dll
(no build feature, no new dependency) exactly as NVENC loads its DLL.

- AVC/HEVC (SDR NV12 + 10-bit HDR P010) and AV1 (RDNA3+, probed); a bounded
  poll retires the libavcodec ~2-frame output hold; native in-place reset().
- Intra-refresh wave (PUNKTFUNK_INTRA_REFRESH), in-band HDR mastering/CLL
  metadata (*InHDRMetadata -> HEVC SEI / AV1 OBU), and a native codec probe
  feeding the GameStream advertisement (windows_backend_is_ffmpeg ->
  windows_backend_is_probed).
- AMD dispatch / advertisement / 4:4:4 are native-only; the libavcodec AMF
  fallback and the PUNKTFUNK_AMF_FFMPEG hatch are removed. FFmpeg serves QSV
  only (its AMF path retained solely as the latency A/B comparator).
- Overload back-pressure: submit bounds in-flight surfaces below the input
  ring, draining finished AUs (buffered for poll, FIFO-preserved) to free a
  slot and retry on AMF_INPUT_FULL instead of tearing the encoder down and
  forcing an IDR; this also closes a latent ring-overwrite corruption seen
  under load on-glass.

Validated on the lab Ryzen iGPU (AMF runtime 1.4.37): HEVC/AVC across a
native reset, HEVC Main10 mastering+CLL SEIs byte-verified, intra-refresh
accepted, a backpressure burst FIFO-clean, and end-to-end via the macOS
client. Measured §5.2 latency A/B: native encode_us p50 ~5 ms (0.31 frame
periods) vs libavcodec ~17 ms (1.01). 4:4:4 stays unsupported (VCN hardware
limit). Live-gated tests skip cleanly on non-AMD boxes.
