5454c02328 Fix explosion.rs over-approximation: use cospan rewrite data for correct covering relations
- Replace all-to-all sub-poset connection with rewrite-based correspondence
- Add compute_subpoint_correspondence() using cone structure for 3 cases:
  identity (1-to-1), contraction (many-to-one), insertion (index shift)
- Add compute_height_maps() for singular and regular height tracking
- Covering relations reduced from 114 to 35 for half_braid (69% reduction)
- Surface 3 (r0,s0,r0): 9 spurious successors → 3 correct successors
- 175 tests passing, 0 failures
- Regenerated fixtures/half_braid_geometry.json with corrected boundaries
