controllerHealthy reads RestartCount (running&&rc>0 -> not ok) + signals needsDwell for no-healthcheck;
verify requires verifyDwell(=3) consecutive ok polls for a no-healthcheck image (real healthcheck
trusted immediately). Closes the F1 hole (alpine crash-loop passed the point-in-time check). Red-proof
+ dwell + real-image tests. No sudoers/orchestration change.

BackupRunner.BackupWithSnapshotHook tails the task log for the 'create storage
snapshot' marker (snapshot mode only) and fires onSnapshot once; localapi flips
/backup/status to 'snapshotted' before 'done' so the controller resumes early.
Phase 0 validated on PVE 9.2.2: marker confirmed, downtime ~24s->~1s (934MB).

internal/localapi: real /backup/due (cadence; due when no successful backup or
newest older than backup.backup_cadence_seconds; false in-window after success;
failed doesn't count) + /backup/status phases (idle|running|done|failed + job
id) + POST /backup single-flight with job id. Drives the controller quiesce loop.
