vgsp-gl: bounded setup-push hold for maturity debugging
sema_gr_setup_hold_ms (default 0, clamp 2000 ms) holds/defer the draw
window while the 60216-byte setup push pin is landing, replacing the
~50% IMMATURE-SKIP lottery. Measured: 2000 ms stalls the ring behind
the unreadable 0x4021004 entry (8 launches then silence), so the
default stays 0; the param is a debug gate only. r1557 with hold=0
produced 64 beef launches and the DS A/B baseline
80000000->a0040a06. Evidence: Handoff cont 8.
