/**
 * Watchdog for eval cell work.
 *
 * A cell's `timeout` bounds time while the Python kernel or JS VM is in control.
 * Host-side bridge calls can {@link pause} the watchdog so waits on
 * `agent()`/`completion()` handles are ignored completely, then {@link resume}
 * starts a fresh timeout window once the runtime gets control back.
 *
 * Pause is reference-counted because multiple handle waits can overlap.
