keep the AP trampoline inert between wakes, and retry failed cores
...
Arm the low frame (copy blob, make executable) only while a core climbs, then zero it and restore RW+NX; the frame stays reserved so cores can be re-woken. startSecondary is one re-runnable attempt; boot retries a non-responding core 3x. Validated the retry path by forcing a first-attempt failure.
