sounddevice is now only imported when actually playing audio through
speakers. All other functions (save_midi, render_score, save) work
without PortAudio installed. Fixes 9 test failures in CI.

instead of knowing fret positions upfront. Updates all docs to use
REPL-style examples with verified output.

Chord names like Cmaj7 and G7 were incorrectly treated as tone names

Dependencies were at the root level instead of under [project] — uv
ignored them entirely. This caused uv.lock to omit pytuning, scipy,
numpy, and sounddevice. API reference pages were blank because
autodoc couldn't import the modules.
Also adds [build-system] so uv treats the project as editable
instead of virtual.

New features:
- Tone.interval_to(other): "perfect 5th", "major 3rd", "octave"
- Tone.midi: MIDI note number (C4=60, A4=69)
- Tone.transpose(n): alias for tone arithmetic
- Chord.transpose(n): shift all tones, preserving quality
- Chord.root: identify the root tone
- Chord.quality: identify the chord quality ("major", "minor 7th")
- Scale.transpose(n): shift to a new key
Cleanup:
- __version__ = "0.3.0"
- __all__ defined — no more ceil/floor leaking
- pyproject.toml: author, license, classifiers, project URLs
319 tests passing.
