First music notation tool in the CLI-Anything ecosystem. Wraps MuseScore 4's
mscore backend following the HARNESS.md 7-phase methodology.
Supports: transpose (by key/interval/diatonic), export (PDF/PNG/SVG/MP3/FLAC/
WAV/MIDI/MusicXML/Braille), part extraction, instrument management, score
analysis (probe/diff/stats), and interactive REPL with undo/redo.
56 tests (39 unit + 17 E2E) — all passing on macOS with MuseScore 4.6.5.
