fix(lean): resolve proofs in TopologicalBraidAdapter

- Unfolded decideGate and used dsimp only to eliminate local let/have bindings in stableSignal_implies_coherent and noCfd_avoids_continuum.
- Used split_ifs to automatically resolve contradictory branches and extracted correct boolean/decidable subgoals.
- Unfolded tensegrityCoherent and applied decide_eq_true_iff.mp to resolve the tensegrity_implies_braid_coherence theorem.
- Updated 0-Core-Formalism/lean/Semantics/AGENTS.md to reflect the completed tasks.
