[1.1.5] - 2026-03-17

Added MP3 embedded ID3v1 metadata reader/writer via Mp3Id3v1Tag and integrated it into engine metadata read/write flow in StubCodecMediaEngine.
Added OGG Vorbis/Opus comment metadata reader via OggParser.readCommentMetadata() and integrated it into StubCodecMediaEngine.readMetadata().
Added FLAC Vorbis comment metadata reader via FlacParser.readVorbisCommentMetadata() and integrated it into StubCodecMediaEngine.readMetadata().
Added Java Sound audio transcoder JavaSoundAudioTranscodeConverter for JDK-only target formats (wav, aiff, au).
Added AIFF embedded text metadata read/write support (NAME, AUTH, (c) , ANNO) via AiffParser.readTextMetadata() and AiffParser.writeTextMetadata().
Added MP4/MOV to M4A audio-track remux route via Mp4MovToM4aRemuxConverter in the video-to-audio conversion hub path.

Updated audio-to-audio conversion routing in DefaultConversionHub to use Java Sound transcoding path (while preserving explicit WAV/PCM routing).
Expanded facade regression coverage in CodecMediaFacadeTest for MP3 embedded metadata and OGG/FLAC metadata read paths.
Standardized metadata merge behavior in StubCodecMediaEngine.readMetadata() to treat embedded metadata as canonical and sidecar values as fallback (putIfAbsent for non-core keys).
Updated metadata write behavior in StubCodecMediaEngine.writeMetadata() so embedded-capable formats (wav, mp3, aif/aiff/aifc) write in-file metadata and remove stale sidecar files.
Expanded metadata regression coverage in CodecMediaFacadeTest and parser-level AIFF coverage in AiffParserTest.

Confirmed metadata and conversion/facade behavior with mvn -Dtest=CodecMediaFacadeTest test.
Confirmed AIFF embedded metadata parser and facade flows with mvn -Dtest=AiffParserTest,CodecMediaFacadeTest test.
