"""Foreground terminal execute must return when the inner wait loop wedges.

#94285: a hung ``_wait_for_process`` (Windows pipe/poll, blocked loop thread)
silently disabled every asyncio timer in the process. ``execute()`` now
bounds spawn+wait with ``run_bounded_sync`` so the wall-clock deadline
survives a wedged wait, and ``on_timeout`` kills the process tree.
