quoije 8267750207 Add ATRAC3+ audio decode via FFmpeg 
- AudioFramer splits concatenated audio payloads into 696-byte frames
  (8-byte PSP header + 688-byte ATRAC3+ data), spanning PES packets.
- Atrac3pDecoder decodes raw ATRAC3+ via JavaCPP FFmpeg, converting
  FLTP output to interleaved S16 PCM.
- CLI 'adecode' command decodes both audio substreams (each a full
  stereo track at 48kHz) and reports stats.
- Validated against Batman Begins: 69 frames/channel, peak ~4900,
  ~64% nonzero samples.

quoije 4821267d0e Add MPS demuxer and FFmpeg H.264 video decode 
- MpsDemuxer parses MPEG-PS packs (0x1BA) into video (0x1E0-0x1EF) and
  audio (0x1BD) PES packets with PTS/DTS at the 90kHz clock.
- VideoDecoder decodes Annex-B H.264 via JavaCPP FFmpeg 8.1.2, splitting
  the stream into access units (one slice NAL per packet) so each send
  yields a frame.
- CLI 'decode' command dumps frame metadata (720x480 YUVJ420P).
- Validated against Batman Begins: 72 frames decoded.

quoije f40fa604a3 Add MPS/MPEG-PS demuxer (H.264 video + ATRAC3+ audio packets) 
- Parse PS packets, PES headers and PTS/DTS timestamps
- 'mps' CLI command samples packets from a stream
- Validated on Batman Begins 00001.MPS (Annex-B H.264 + 2-channel ATRAC3+)

quoije b09e23208a Parse PLAYLIST.UMD: streams, chapters and timestamps 
- Add little-endian readers to UmdIsoFile
- Playlist parser (streams + chapter markers) ported from JPCSP
- dump command now lists streams, durations and chapter markers
- Unit test for chapter/timestamp mapping

quoije 797b0507bd Scaffold Java 21 multi-module project with UMD ISO + SFO parsing 
- Gradle Kotlin DSL multi-module (core, ui, cli) with JPMS modules
- UMD ISO 9660 reader (UmdIsoReader/UmdIsoFile + sector devices)
- SFO (param.sfo) parser
- 'dump' CLI command: metadata + recursive file listing
- JUnit 5 + AssertJ tests (SFO and ISO reader)
- Switch license from MIT to GPL-3.0-or-later
