TASK-004: Implement Simulator driver

RFC: RFC-0005 - Deterministic Simulation Testing
Component: Simulation Core
Estimate: l

Description

Create Simulator with event queue (BinaryHeap). Implement tick() that processes next event. Support run() and run_until().

Acceptance Criteria

• AC-001: Same seed produces identical simulation results
  • Verification: Run simulation with seed=42 twice, verify identical event sequence and final state
• AC-007: Simulate 1 million operations in under 60 seconds
  • Verification: Benchmark 1M ops simulation on standard hardware

Dependencies

Depends on: TASK-001, TASK-002, TASK-003
