Add Strix camera discovery system with comprehensive database

This commit adds the complete Strix IP camera stream discovery system:
- Go-based API server with SSE support for real-time updates
- 3,600+ camera brand database with stream URL patterns
- Intelligent fuzzy search across camera models
- ONVIF discovery and stream validation
- RESTful API with health check, camera search, and stream discovery
- Makefile for building and deployment
- Comprehensive README documentation
