- web_server.py: after proc.poll() returns a non-None exit code, call
proc.wait() to reap the child and move the entry from _ACTION_PROCS
to _ACTION_RESULTS. Previously .poll() alone left <defunct> zombies.
- meet_bot.py: terminate and wait on the pcm_pump subprocess (paplay/
ffmpeg) during the finally-block teardown. Previously leaked on every
normal bot exit.
- tests: add test_action_status_reaps_completed_process and
test_action_status_ignores_wait_failure covering both the happy path
and the wait()-raises-OSError edge case.
