Tenuo AgentQL Performance Benchmark

Measures and verifies the performance claims made in PERFORMANCE.md:
- Authorization latency (~0.005ms per check)
- Throughput (268,000+ checks per second)
- Memory overhead (~50 KB per agent)
- Workflow overhead (<0.03%)
- Delegation chain overhead

Run this to verify claims on your system. Results will include system
specifications for reproducibility.
