Chord names like Cmaj7 and G7 were incorrectly treated as tone names
because they contain digits. Now tries chord name lookup first. v0.5.1.

Supports single tones and chords, with --synth (sine/saw/triangle),
--duration, and --temperament flags. Bumps version to v0.5.0.

CLI (pytheory command):
pytheory tone C4 — frequency, MIDI, overtones
pytheory scale C major — notes and intervals
pytheory chord C E G — identify, harmony, tension
pytheory key C major — full key analysis with diatonic chords
pytheory fingering Am — ASCII guitar tab
pytheory progression C major I V vi IV — build from Roman numerals
pytheory detect C D E G — detect the key
Jupyter notebook (examples/tutorial.ipynb):
46-cell interactive tutorial covering tones, scales, modes, keys,
chord analysis, progressions, world music systems, guitar fingerings,
and building a song from scratch.

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.
