chore: rm fault proofs

[jackchuma]

Summary

• Removes the onchain fault-proof and Cannon/MIPS surface: FaultDisputeGameV2, PermissionedDisputeGameV2, MIPS64, PreimageOracle, Cannon libraries/interfaces, and their ABI/storage snapshots and tests.
• Simplifies system deployment around the multiproof AggregateVerifier: implementations now cover the shared DelayedWETH, AnchorStateRegistry, DisputeGameFactory, portal/bridge contracts, and multiproof verifier contracts without deploying MIPS, preimage-oracle, or fault-game implementations.
• Updates deploy configuration to drop fault-game, output-oracle proposer/challenger, and preimage-oracle fields; delayedWETHWithdrawalDelay now drives the retained delayed-WETH withdrawal delay, and starting anchors come from the multiproof genesis config.
• Generalizes the anchor/dispute-game interfaces so AnchorStateRegistry works against IDisputeGame instead of the removed fault-dispute-game interface, and trims bridge types/errors down to the remaining aggregate-verifier flow.
• Updates deployment, portal, dispute-game, and anchor-state tests to use AggregateVerifier based games, while removing obsolete fault-game, Cannon, preimage-oracle, LibGameArgs, LibPosition, and invariant coverage.
• Refreshes interface checks, validation exclusions, semver locks, and snapshots to match the slimmer contract set.
