Brandon Schneider e5386c4f5a feat(lean): BraidSpherionBridge — SpherionState ↔ BraidState equivalence
Bridge module connecting:
- SpherionState (Mountain/MMR/betaStep/rgFlow)
- BraidState (8 strands/crossStep/BraidReceipt/encodeReceipt)

Key content:
- SpherionSpike inductive (Mountain + crossPair Fin 4)
- IntNodeToPhaseVec bridge function
- spikeToStrandUpdate, strandFlow operations
- crossPair lemmas (0→(0,1), 1→(2,3), 2→(4,5), 3→(6,7))
- braidCross_phase_linear, Mountain_merge_apex_add lemmas
- braidCross_merge_correspondence (admit — TODO(lean-port): complete)
- k_spike_step_count (admit)
- receipt_correspondence, receipt_encode_stable (admit)
