Updates seismic-evm dependency and adds code override rejection with comprehensive test coverage.

Phase 2

• Cargo.lock:2101,3934,3952,6228,6265,12204,12720 — Multiple dependency downgrades (socket2 0.6.1→0.5.10, windows-sys 0.59.0→0.48.0, etc.) alongside the seismic-evm update. While likely necessary for compatibility, verify these downgrades don't introduce security vulnerabilities or missing features that the codebase relies on.

Phase 3

• crates/seismic/rpc/src/eth/ext.rs:197 — Extra blank line added with no functional change.

The error handling implementation looks solid — properly integrated into the existing error system with appropriate JSON-RPC mapping. The test coverage is comprehensive, hitting all three RPC endpoints that accept state overrides (eth_call, eth_estimateGas, eth_simulateV1). Code override rejection is a reasonable security measure for Seismic's privacy model.

LGTM — the functionality is correctly implemented and well-tested.
