An agent's commands run through a wrapper shell whose command line contains the
pattern being searched for, so `pgrep -f 'pilot\.py'` matches the shell running
that very pgrep, and `pkill -f 'fly_session|pilot\.py'` kills it mid-script. In
one session this killed two running scripts and twice made an "is it already
running?" guard answer yes because it had found itself. The [p]ilot bracket trick
does not help, because the real invocation appears on the wrapper's command line
too.
Recorded with what works instead: pgrep -x on the exact name, or ps -eo args
filtered against the snapshot-bash path that every wrapper carries, then kill by
explicit pid.
