Bench session stops the anland app at start and relaunches it at stop, so FCL keeps the foreground.

# 3. releases those requests and re-pins (pin_clocks.sh);
# 4. force-stops the anland desktop app, recording whether it ran. Its activity takes the
# foreground back whenever it is paused, so FCL launched over it never reaches the world
# (2026-10-08: a job's own end-of-run relaunch left it up and the next job got 0 of 4 worlds).
# stop: starts every service that was running before start, and verifies each is running again;
# relaunches the anland app if it ran before start (keeps anland usable).
# ALWAYS run it - callers trap it on EXIT/INT/TERM, so an interrupted session restores too.
# Kernel-level protection (LMh, BCL, kernel thermal trip points) is never touched; the run's sampler
# (freq_sampler.sh -> freqcheck.py) shows any frequency collapse, and a collapse ends benchmarking.
