Guard seat test scripts behind __main__; clean _t_* cron output residue

Browse Source 
Both harnesses executed top-to-bottom on import, so anything collecting
them (pytest, a glob import) ran live-store side effects. main() guards
plus finally-block cleanup of the _t_* cron output dirs the fabricated
jobs leave behind.

Calls cron.monitor.check_monitor and cron.scheduler._apply_monitor_gate directly
against fabricated job dicts and throwaway monitor scripts. No live job touched,
no agent woken. Exit codes: 0 = all assertions held, 1 = mismatch.
Guarded behind __main__: importing this module (e.g. by pytest collection)
must not execute it or touch the live cron store.
