v0.2.0: Multi-Format Audio Intake, Cache & UI Enhancements

What's new in v0.2.0

Audio intake and matching

• Added support for .flac, .m4a, .ogg, .opus, .wav, and .aiff file formats in the intake scanner alongside .mp3.
• Added a local SQLite fingerprint cache (cache.db) that records file modification times and fingerprint hashes, skipping Chromaprint calculations on unmodified files during library rescans.
• Added multi-disc numbering heuristics to detect disc prefixes (101, 1-01) and continuous multi-disc track sequences.
• Added multi-folder intake with Ctrl-drag to append files without clearing the staging table.

Staging table and metadata tools

• Added track editing dialog to inspect and manually edit title, artist, album, year, and track numbering directly from the table.
• Added title cleaning options to strip bracketed text, track numbers, and extra whitespace.
• Added duplicate detection across fingerprints, metadata tags, and filename stems, with single-folder consolidation for unique tracks.
• Added cover art injection to copy one track's artwork across every loaded file.
• Added instant text search and contextual sibling filtering by artist, album, folder, or status.

Interface and documentation

• Relocated the theme toggle to the bottom status footer.
• Added integrated offline user guide (help.html) accessible directly from the options bar.
• Added multi-resolution application icon (app_icon.ico) with dedicated frames from 16x16 to 256x256 for Windows Start Menu, Taskbar, and Desktop shortcuts.
