fix(satellite): Selbstdiagnose fuers Netz — warnt bei Docker-/NAT-Netz
Symptom: Satellit fand nur Docker-Container (192.168.65.x / 172.18.x) statt der echten LAN-Geraete. Ursache ist kein Bug, sondern das Deployment-Netz: auf Docker Desktop (Mac/Windows) ist network_mode:host das Docker-VM-NAT, nicht das echte LAN — mDNS/SSDP erreichen die realen Geraete nicht. - satellite.py: _net_context() ermittelt primary_ip + alle IPs und WARNT, wenn der Satellit in einem Docker-/NAT-Netz laeuft (192.168.65.x oder 172.16-31.x). Netz- Info wird in sat_hello + sat_devices mitgeschickt und beim Start geloggt. - Diagnostic: zeigt Netz (primary_ip) pro Satellit + eine rote ⚠-Box mit der Warnung, wenn er im falschen Netz sitzt. - README/compose: klar dokumentiert, dass der Satellit im ECHTEN Ziel-LAN laufen muss (Linux Docker Engine ODER nativ python satellite.py); Docker-Desktop-Falle. py/node clean.
