The prune service and healthcheck force-remove ALL containers via
"docker ps -aq | xargs -r docker rm -f", but this includes the CI
job container itself (named GITEA-ACTIONS-TASK-*). Removing it causes
"RWLayer of container is unexpectedly nil" errors and kills the
active CI job.
Exclude containers whose name starts with GITEA-ACTIONS-TASK from
the force-remove step. Use "docker ps -a --format" with name filtering
instead of "docker ps -aq".
