feat(2w): W0.5 WC3 snapshot/restore helper (warmsnap.py)
runner/harness/warmsnap.py: raw per-volume tar of an app's stack volumes while
UNDEPLOYED, under /var/lib/ci-warm/<recipe>/ (meta.json + volumes/<vol>.tar);
one last-good, atomic dir swap; restore clears+untars each volume back. Asserts
undeployed (consistency). Reused by WC1.1 (pre-upgrade keycloak snapshot) + WC5.
+5 unit tests (48 unit pass).
LIVE round-trip PROVEN on warm keycloak: create marker realm -> undeploy ->
snapshot (mariadb+providers vols) -> deploy -> delete marker (mutate DB) ->
undeploy -> restore -> deploy -> marker realm BACK; keycloak healthy. WC3 core.
