Add CheckResult (LockPresent, ErrorsFound) and RunCheck. subsetPct>0 passes --read-data-subset N% to limit data reads. Stderr is sniffed for "Found stale lock"/"locked" to set LockPresent; a non-zero exit from restic is absorbed as ErrorsFound=true rather than an error so the caller can always persist last_check_status. Tests cover lock detection, exit-1 absorption, and subset-arg plumbing.
