Phase 1.4

Depends on #13

Files: solver/mates/generator.py (Create), tests/mates/test_generator.py (Create)

Scope: SyntheticMateGenerator wraps SyntheticAssemblyGenerator, reverse-maps joints to mate combinations (REVOLUTE->Concentric+Coincident(plane), BALL->Coincident(point), etc.). Generates GeometryRef with realistic geometry. Injects noise: redundant/missing/incompatible mates at configurable probabilities. generate_mate_training_batch() produces mate-level training examples.

Acceptance Criteria:

  • Reverse mapping for all 6 joint types
  • Round-trip through analyze_mate_assembly()
  • Redundant/missing mate injection
  • Deterministic with seed
  • Tests, ruff, mypy all pass
