tools/cuda-ab: memset_probe + wedge_recover forensics clients (session 10)

memset_probe: linear 8 MB cudaMemset + D2H with first-bad offset and a
4 KB page map (correct / other / malloc-prefill) - separates 'fill
under-delivered' from 'readback delivered wrong pages'; standalone green,
bisects the memcpy_roundtrip memset phase.

wedge_recover: launch+verify loop that on failure sleeps N seconds and
retries the same iteration (same context), reporting per-iteration
attempts and launch times - tests whether an idle gap heals the per-boot
no-execute wedge (r409 log shows a ~37 s client-side gap healed a wedged
run).

Also ships the missing inplace_scale run binary (its source landed in
7685d1b3).
