Fast (~1-3s) endpoint that gathers network info about a device before full stream discovery. Runs ping first, then parallel probes. Features: - Ping with ICMP + TCP fallback (works without root) - Reverse DNS hostname lookup - ARP table MAC address + OUI vendor identification (2403 entries, 51 camera vendors) - mDNS HomeKit detection (camera/doorbell, paired status) - Extensible Prober interface for adding new probe types - 3-second overall timeout, parallel execution Response includes "type" field: - "unreachable" - device not responding - "standard" - normal IP camera (RTSP/HTTP/ONVIF flow) - "homekit" - Apple HomeKit camera (PIN pairing flow)
