- Add request logging middleware to main.go - Add debug handler with health, config, stats, and test-dns endpoints - Add detailed logging to DynDNS handler - Add logging to Technitium DNS client - Add database Ping() and GetStats() methods - New endpoints: - /health - detailed health status with database and DNS checks - /debug/config - sanitized configuration - /debug/stats - database statistics - /debug/test-dns - live DNS test endpoint This will help diagnose production issues with DNS updates.
