Unify network bring-up into the micronet daemon - #2
Merged
Conversation
Replace configure-ethernet and configure-dhcp with one JSON-configured daemon that probes foreign DHCP, pings gateway.ip, and applies client, gateway, or static .252 modes with dnsmasq only when needed. Co-authored-by: Cursor <cursoragent@cursor.com>

- Drop port=0 from dnsmasq.conf so the DNS listener stays on; we hand out option:dns-server = gateway.ip and ARCHITECTURE describes DHCP+DNS. - Poll the interface every ~3s in client mode and update the status snapshot when dhclient finally acquires a lease, so micronet check liveness sees a non-empty cidr instead of looping restarts.

Fail closed on probe errors and validate DHCPOFFER xid/chaddr/opcode. Own dnsmasq and dhclient via pidfiles, start dhclient -nw, and periodically re-probe in gateway mode so a later foreign DHCP server makes us yield. Live liveness, real CIDR, teardown CLI, and legacy configure-* check fallback. Co-authored-by: Cursor <cursoragent@cursor.com>
