Two bugs caused the log file to never be written: 1. is_service_container() used regex '^decky-\d+-\w' which only matched the old decky-01-smtp naming style. Actual containers are named omega-decky-smtp, relay-decky-smtp, etc. Fixed by using Docker Compose labels instead: com.docker.compose.project=decnet + non-empty depends_on discriminates service containers from base (sleep infinity) containers reliably regardless of decky naming convention. Added is_service_event() for the Docker events path. 2. The collector was only started when --api was used. Added a 'collect' CLI subcommand (decnet collect --log-file <path>) and wired it into deploy as an auto-started background process when --api is not in use. Default log path: /var/log/decnet/decnet.log
