clawbot 68fbebd0c5 fix: use os.ErrNotExist instead of errors.New() for file-not-found detection in checkers ... errors.Is(err, errors.New("file does not exist")) can never match because errors.New creates a unique value each time. Replace with os.ErrNotExist which is the standard Go sentinel for file-not-found errors. Fixes both mfer/checker.go and internal/checker/checker.go.		2026-02-08 12:02:31 -08:00
