Subject: [PATCH] feat: harden game settlement and staking paths for issues
 522-525

Strengthen on-chain game settlement with replay-safe payout state transitions, admin-gated stake limits, safer timeout arithmetic, and strict puzzle reward amount validation. Add regression tests and updated snapshots to cover settlement replay, admin authorization, and invalid amount edge cases.
