def89ffe59 add LAN accessibility indicator for services
Show whether each service is reachable from the network or bound to
localhost only. Dashboard displays green "LAN" or amber "local only"
badge next to each healthy service. Unified TCP check function,
concurrent health+LAN probes.

a29e4aeb96 fix LAN discovery: instance-based self-filter and multicast port reuse
Replace IP-based self-announcement filtering with a per-process instance
ID (pid ^ timestamp) so multiple instances on the same host can discover
each other. Enable SO_REUSEPORT for multicast socket binding on Unix.
Add multicast address validation on configured group.

c410945222 add LAN service discovery via UDP multicast
Numa instances on the same network auto-discover each other's .numa
services. No config, no cloud — just multicast on 239.255.70.78:5390.

- PeerStore with lazy expiry (90s timeout, 30s broadcast interval)
- DNS resolves remote .numa services to peer's LAN IP (not localhost)
- Proxy forwards to peer IP for remote services
- Graceful degradation if multicast bind fails
