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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
