vgsp-gr r597: emit the captured prelude's SEM_EXECUTE ACQUIRE groups ahead of the rebuilt window (default off)
The verbatim prelude replay breaks the launch (r599: qmd_rel=0 after an
8.9 s stall), so the acquire cannot be taken by replaying the prelude.
This takes only the wait method groups - C46F addr 0x5c count>=5 with
EXECUTE&7 != 1, and C5C0 SET_REPORT_SEMAPHORE A..D with a non-release op -
and copies them verbatim before the proven init+window+PCAS+release
block, leaving the window untouched.
Gate: gsp_phys_rmcall_gr_acq (default 0). Live A/B on r601: the mail
launch's prelude carries ZERO acquire groups (the C5C0 prelude is inline
parameter data + release only), so emitted=0 and the VADD race is
unchanged - the driver assumes its relocation copies precede the launch
without an engine-visible wait.
