The old script hit 192.168.1.86:3000 which never existed on this LAN.
Real Gitea lives on 192.168.0.82:3000. Also prefer GITEA_TOKEN over
embedding a password; GITEA_PASS remains as a fallback.
Godot reads get_cmdline_user_args() which only contains args after '--'.
Without the separator, NetworkManager never saw --server and the
ENetMultiplayerPeer never bound UDP 7777.
Verified on 192.168.0.89: udp/7777 now listening.
