reclaimable. Existing `GITEA-ACTIONS-TASK` name-prefix and `status=exited`
guards are retained for unlabeled objects.
REQ-2: Introduce a single shared cleanup script
(`runner-cleanup.sh`, templated next to the healthcheck script) invoked with
`--tier routine|pressure|critical`. It replaces all inline prune logic in
`docker-prune.service` and the healthcheck. Every prune is scoped: volumes and
networks get `label!=`/`until=` filters at every tier (no unfiltered volume or
network prune remains); images matching `gitea_runner_keep_images` are never
removed, so warm base layers survive critical pressure.

REQ-3: Watermark-tiered behavior: `routine` (timer) prunes aged resources;
`pressure` (disk >= warn) prunes unowned resources older than 1h; `critical`
(disk >= critical) drops age limits but still honors leases, keep-images, and
never removes running or `GITEA-ACTIONS-TASK` containers.
