feat(shapeseq): implement Layer 2 — all 8 primitives and chain runner
primitives.js (505 lines): All 8 sequencing primitives extending
Primitive base class:
- EuclideanRhythm: Bjorklund-distributed trigger patterns
- ProbabilityGate: PRNG-based trigger filtering + accent assignment
- PitchWalker: stateful constrained random walk with gravity
- Ratchet: probabilistic step subdivision (1-4x)
- SwingGroove: alternating-step timing offsets (max triplet feel)
- DensityMorph: trigger placement with clustering control
- IntervalLock: 11-scale pitch quantizer (chromatic→diminished)
- VelocityShaper: 5 curve types with depth/phase control
Includes PRIMITIVE_REGISTRY for chain builder UI.
chain.js (319 lines): Sequential pipeline chain evaluator.
Buckets primitives by category (generators→processors→converters→
timing), forks deterministic PRNG per primitive, merges multiple
generators via additive (OR) or multiplicative (AND) mode
(configurable in real time). Flat param distribution by chain
position. Full state serialization for freeze support.
