[EPIC] RC2: Zero-Knowledge Proof Production

[Steake]

Epic Goal: Deploy production-ready ZK-SNARK system with real cryptographic proofs.

Scope: Implement full R1CS constraints for battle and state circuits, conduct trusted setup ceremony, optimize proof generation.

Success Criteria:

• ✅ Battle proofs generated in <30s
• ✅ State proofs generated in <20s
• ✅ Verification keys published and auditable
• ✅ Trusted setup ceremony completed

Dependencies: Requires RC1 ZKP architecture (#40)
