Verify 8-tick performance compliance.

Check that all hot path operations complete within 8 ticks:
1. Run performance tests: `make test-performance-v04`
2. Review performance test output
3. Verify p95 latency ≤8 ticks
4. Check for any operations exceeding budget
5. Review OTEL metrics for tick distribution

If any operation exceeds 8 ticks, investigate and optimize.
