bsncubed 8a6cb53e3b Step 7.3: decode HLS TS segments to PCM (own TS demux + AAC decoder)
- main/decoder: MPEG-TS demux (packets reassembled across HTTP chunks,
  PAT -> PMT -> first ADTS-AAC PID, PES headers stripped) feeding the
  esp_audio_codec simple AAC decoder (ADTS, AAC-Plus enabled for HE-AAC
  v1/v2 variants). 7.3 only counts and logs PCM per segment.
- esp_audio_codec pinned to ~2.5.0: 2.6+ needs P4 rev >= 3 (this board
  is rev 1.3). Noted in CLAUDE.md, also for esp_audio_effects < 1.4.
- The library's combined TS decoder lost ~8% of the frames (segments
  decoded to 7.9-9.6 s, "decode error -1"); with the own demux every
  segment is sample exact: 441344 / 440320 frames = 10.008 / 9.985 s,
  matching EXTINF 10.0078 / 9.9846 (431 / 430 AAC frames), no errors.
