[TIME-TRAVEL] [TEST] Performance benchmark: Snapshot overhead

[dotandev]

Description

We need to ensure snapshots don't degrade the core simulation performance beyond acceptable limits.

Requirements

• Add benchmark tests in simulator/benches/snapshot_bench.rs.
• Compare execution time of 1000 host functions with vs without --snapshots.
• Report overhead as a percentage.

Acceptance Criteria

• Benchmarks run in CI to prevent performance regressions.
• Results are exported to CSV for tracking.

Estimated File Changes: 2 (simulator/Cargo.toml, simulator/benches/snapshot_bench.rs)
