Implements a new backend targeting Coq (Gallina) which generates a protocol specification including: - Inductive types for Roles and domain-specific Enums. - Abstract evidence and Witness records that accumulate causal history. - An Explicit State Machine (ESM) modeling valid transitions. - Handling of commit-reveal patterns and public guards. Includes integration with `GoldenMasterTest` and generated examples.

Implemented a Gallina backend that transpiles Vegas IR to Coq modules. The backend generates dependent types to model the game state and valid transitions, ensuring that witnesses for actions carry proofs of their dependencies and guards.
