Fix repeat timing: don't double-drive IO suspensions

Browse Source 
The value_to_js resume handler was calling _driveAsync on re-suspension,
but the JS driveAsync caller also processes the returned suspension.
This caused the second wait in each iteration to fire immediately (0ms)
instead of respecting the delay.

Fix: resume handler just returns the suspension object, lets the JS
driveAsync handle scheduling via setTimeout.

Verified: repeat 3 times add/wait 300ms/remove/wait 300ms produces
6 transitions at correct 300ms intervals (1504ms total).
