Module simulation 

Multi-turn simulation support for eval case generation and replay.

This module implements Phase 6 (US4) of spec 043-evals-adv-features:

• ActorSimulator drives a simulated user across multiple turns.
• ToolSimulator produces schema-valid tool responses, backed by a StateRegistry of bounded-history StateBuckets.
• run_multiturn_simulation orchestrates an agent ↔ actor dialogue up to max_turns or goal-completion.

All surfaces gated by the crate-level simulation feature. Tests live in eval/tests/simulation_test.rs, eval/tests/simulation_state_test.rs, and eval/tests/us4_end_to_end_test.rs.
