vgsp-gr: retirement wait - whole-window footprint with adaptive exits
Footprint-by-inference (max-reloc contiguous run, launch-page exclusion)
failed twice: the fill's candidate list ends with the launch's own bank/
param pages, so the inferred output run was 3-4 pages (r150/r151: '0/3
pages changed after 72 ms (no writes)') and the wait exited before any
real output landed. Replace with a whole-window count over every resolved
data page plus cheap adaptive exits:
- all pages changed -> done (one poll in the normal case),
- partial count stable for 3 polls -> stores settled,
- no change for 600 ms -> no output for this launch,
- hard cap 1.5 s.
No inference, no exclusion list, bounded cost.
