Expand accepted audio formats beyond MP3/WAV/OGG to include FLAC, AAC, M4A, AIFF, OPUS, WMA, WebM, ALAC, APE, WavPack, DSF, and DFF. The HTML5 Audio player already handles whatever the browser supports. Changes: - BeatUploader: accept audio/* instead of hardcoded format list - shared-storage: add MIME type mappings for all common audio formats Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
