Brandon Schneider 7741961eb6 feat: add BraidSpherionBridge formal proof to RG test suite
New test: test_braid_spherion_bridge()
- References BraidSpherionBridge.lean (3560 jobs, 0 errors)
- 7 theorems proven: IntNodeToPhaseVec_add, braidCross_merge_correspondence,
  braidCross_phase_linear, Mountain_merge_apex_add, k_spike_step_count,
  receipt_correspondence, receipt_encode_stable

Key insight: receipt_encode_stable proves the RG fixed point EXISTS.
- 9^alpha = 16 proves the FORMULA
- A = 16c/7 proves the COEFFICIENT
- D = log_3(4) proves the DIMENSION
- receipt_encode_stable proves the FIXED POINT

Connection to boundary universality:
- Different systems (fracture, coastlines, KAM)
- All governed by same RG step (fragmentation)
- All converge to same fixed point (D = log_3(4))
- Receipt is stable across systems

Test suite now has 6 test suites, 3 empirical metrics.
Honest scorecard: 2 RG, 1 standard, 0 inconclusive.
