All 4 surfaces updated and tested. Here’s the summary:

Command: ww network discover

ww network discover              # Quick: ARP table + MAC OUI vendor lookup
ww network discover -r           # + reverse DNS hostnames
ww network discover -p           # + port probe + device type guessing
ww network discover -r -p        # Full discovery
ww network discover -s 10.0.0.0/24  # Custom subnet

What it does:

1. Gets local IP via UDP socket trick (no traffic sent)
2. Parses arp -an table (numeric, no DNS timeout)
3. Enriches with MAC OUI → vendor name (Apple, Xiaomi, TP-Link, Espressif, etc.)
4. -r: reverse DNS hostname resolution
5. -p: probes 8 common ports (SSH, HTTP, mDNS, VNC, AirPlay, iPhoneSync) → guesses device type
6. Filters out multicast/broadcast, sorts by IP
7. Prints aligned table
