feat(detection): add centralized protocol detection module

- Created ts/detection module for unified protocol detection
- Implemented TLS and HTTP detectors with fragmentation support
- Moved TLS detection logic from existing code to centralized module
- Updated RouteConnectionHandler to use ProtocolDetector for both TLS and HTTP
- Refactored ACME HTTP parsing to use detection module
- Added comprehensive tests for detection functionality
- Eliminated duplicate protocol detection code across codebase

This centralizes all non-destructive protocol detection into a single module,
improving code organization and reducing duplication between ACME and routing.
