BusyBox flock kennt nur -n (non-blocking), nicht -w/--timeout.
Der alte Code 'flock -w 900' schlug fehl → Skript fiel sofort in
'fahre ohne Lock fort' und lief ohne Race-Schutz.

Fix: -n mit 900s Retry-Loop (1s Intervall) = effektiv 15min Timeout.
Der Lock wird jettt korrekt gesetzt, parallele Downloads sind serialisiert.
