# Reconfigures the PW-DocserverWorker scheduled task for self-healing:

#   - StartWhenAvailable (catch up if a trigger was missed)
#   - a repeating safety trigger every 5 min with MultipleInstances=IgnoreNew,
#     so if the worker process ever dies (crash, manual kill, missed boot
#     trigger) it relaunches within ~5 min instead of waiting for a reboot
#   - keeps AtStartup + SYSTEM/Highest (current working config)
# Idempotent: safe to re-run. Run as Administrator.
