Tanmoy Sarkar 9c4d81726d feat(companion): Add parent-death cleanup for manager and companions ...

Stop orphaned processes from lingering when their parent dies.

set_parent_death_signal arms Linux prctl(PR_SET_PDEATHSIG) so a process is
signalled the moment its parent exits, returning False off Linux so callers
fall back to polling getppid.

The manager records its parent pid, arms a SIGTERM parent-death signal, and
checks getppid each tick: if the arbiter dies, the manager stops its companions
and exits instead of running on under a dead arbiter. Each companion arms the
same parent-death signal and rechecks getppid right after the fork, exiting if
the manager already died before the signal was armed.
