Every song now has: stereo panning, convolution reverb (plate/cathedral),
humanize (0.2), detune (8-12) on pads, sidechain on electronic tracks,
lowpass on bass, delay on leads. No melodies changed — just better sound.

Gamelan uses its own tone names (nem, pi, barang, etc.), not Western
note names. Fixed tonic from C4 to nem4 and added pelog nem/barang
modes. Replaced miyako-bushi with iwato and kumoi (actual scale names
in the system). Added ValueError to exception handling.

New features:
- Chord.from_name("Am7") — build chords from chart names
- Chord.__str__() — prints "C major" instead of raw tones
- Interval constants: Interval.PERFECT_FIFTH, MAJOR_THIRD, OCTAVE, etc.
- PROGRESSIONS dict: 8 common progressions as Roman numeral tuples
("I-V-vi-IV", "ii-V-I", "12-bar blues", etc.)
- Tone.enharmonic: C# → "Db", natural notes → None
- Key.__str__(): "C major"
Fix: docs CI now installs all dependencies (uv sync --group docs)
so autodoc can import pytheory modules. API reference pages were
blank on GitHub Pages because pytuning/scipy weren't installed.
New example: examples/explore.py — comprehensive demo of the full API.
393 tests.
