Summary
This PR sets up Kani formal verification in
stealth-registry/src/proofs/to prove correctness-critical invariants.Proved Invariants
proof_register_then_resolve): Proves that registering a 64-byte stealth meta-address payload and resolving it immediately returns the exact registered payload.proof_no_duplicate_keys): Proves that active storage entries maintain key uniqueness across mutations.proof_expiry_monotonicity): Proves that TTL extensions during registration and lookup operations result in monotonically non-decreasing expiry ledgers (new_expiry >= old_expiry).CI & Documentation
