MUSIC-MIND: generative harmony, event pipes, and intelligence axes

Three organs answer "what would make richer, more interesting music across all 178 genres" (docs/MUSIC-MIND.md):

• engine/theory.js (CsdTheory) — the harmony brain: modes, minimal- motion voice leading (close/open/drop2/quartal/cluster), and a functional-harmony progression generator whose `adventure` knob gates diatonic…

• engine/pipes.js (CsdPipes) — the scheduler as pipes: state.pipes runs ten composable seeded transforms (harmonize, echoCanon, strum, ghost, callResponse, densityArc, sweepArc, vibratoSwell, throwFx…

• rhythm intelligence — new clave/cell bass vocabulary (tresillo, son, hemiola, charleston), per-cycle bass-cell mutation, and melody rhythm cells (dotted pairs / tresillo / 3-3-2), all under state.rhythm…

• The genre space grows the axes: deriveMind() infers every anchor's theory/pipes/rhythm from what it already declares (progression pool -> adventure/color, kit pool -> complexity, models -> pipes), with an…
