Forward termination signals to the test process group.

On SIGTERM, the helper signals its child process group, which contains the deadline wrapper. The wrapper starts scripts/run_tests.sh in a separate session and does not handle SIGTERM, so it can exit and release the helper’s lock while the suite continues. A later queued suite can then overlap. The old direct route was unqueued, so this is a gap in the new queue guarantee, not a new overlap mode relative to the base.

Review comment at @.githooks/pre-push at line 103:
Update the signal handling in run_with_deadline.py so SIGINT, SIGTERM, and
SIGHUP are forwarded to the child process group running scripts/run_tests.sh,
rather than allowing the deadline wrapper to exit while the suite continues.
Handle signals received before the child is created by recording and forwarding
them once it starts; preserve the helper’s lock until the test process has
terminated.
