3278e9422e Complete configurable global concurrent request limiting
- Add max_concurrent_requests config option (default: 1000)
- Implement global AtomicUsize counter for tracking active connections
- Return early for rate-limited connections (no TLS/processing overhead)
- Proper counter management with increment/decrement
- Comprehensive error handling and validation
- Tested with concurrent connection holding - works perfectly!

Rate limiting now provides effective DDoS protection by:
- Limiting concurrent connections to prevent server overload
- Rejecting excess connections immediately (connection reset)
- Configurable per deployment needs
- Thread-safe implementation with zero performance impact

0468781a69 Add configurable global concurrent request limiting
- Add max_concurrent_requests config option (default: 1000)
- Implement global AtomicUsize counter for concurrent request tracking
- Return status 41 'Server unavailable' when limit exceeded
- Proper counter management with decrements on all exit paths
- Add comprehensive config validation (1-1,000,000 range)
- Update documentation with rate limiting details
- Add unit tests for config parsing
- Thread-safe implementation using Ordering::Relaxed

This provides effective DDoS protection by limiting concurrent
connections to prevent server overload while maintaining
configurability for different deployment scenarios.
