fedac/native: lanserv LAN dev server (http + mdns/bonjour) + ssh in oven builds master
- lanserv.c: HTTP control endpoint (status/logs/piece push/jump) on :80 and an mDNS responder so the device answers at <slot>.local and shows up in Bonjour browsers via _http._tcp, printer-style - /tmp/ac-jump watcher in the main loop: shared hot-reload trigger for lanserv HTTP and ssh (echo notepat > /tmp/ac-jump) - docker-build.sh: bundle dropbear (already on the builder image) so OTA builds get the ssh daemon notepat already auto-starts on wifi; bake keys/authorized_keys and switch dropbear to key-only when present; fix /etc/passwd to full 7-field form (home + shell for dropbear) - persist the dropbear host key on the EFI partition for a stable ssh identity across reboots - scripts/dev-push.sh: curl-based push + reload loop (--watch)
