New benchmarks:
- http_benchmark.lux: Minimal HTTP server for throughput testing
- Use with wrk or ab for request/second measurements
- Target: > 50k req/sec
- json_benchmark.lux: JSON parsing performance test
- Token counting simulation
- Measures iterations per second
These complement the existing recursive benchmarks (fib, ackermann)
with web-focused performance tests.
