Woodpecker's k8s backend deletes each workspace PVC when a pipeline
ends, but ceph-filesystem has reclaimPolicy Retain, so every finished
pipeline left a Released PV pinning a CephFS subvolume — 191 of them
by 2026-07-16 (found in #262). New ceph-filesystem-ephemeral class
(identical parameters, reclaimPolicy Delete) used only by the CI
workspace volumes; production PVCs keep the undoable Retain default.
Existing Released woodpecker-ci PVs are swept out-of-band (they
predate this class and are unaffected by it).
