Address re-review: AAC re-encode, probe fallthrough, HDR detection

- Android non-AAC audio is now transcoded to AAC (matching iOS) via a
  source-decoder -> AAC-encoder pre-pass that captures the encoder's
  output format before the muxer starts, then writes buffered samples
  after the video pipeline finishes. Falls back to dropping audio if
  the transcode fails.
- compress.ts wraps probe() in try/catch and falls through to
  passthrough on failure instead of throwing.
- Probers expose isHDR (HLG/PQ via color transfer, plus Dolby Vision
  codecs/mimes); shouldCompress forces compression for HDR sources so
  the SDR BT.709 path always runs. Also sets
  KEY_COLOR_TRANSFER_REQUEST=SDR on the Android decoder (API 31+) so
  HDR sources tone-map to SDR pixels instead of being mislabeled.
