vgsp: m74 - R1 booking before F2 image init (context-image aux pointers) + CWD_FS readback
The one-shot GR context-image initializer (0x52a94f8, pEngCtx+0x135) runs in
F2's mapped-MAIN promote and consumes the per-VAS vaLists at that moment. With
R1 after F2 the image carries zero PATCH/PM/priv-map/global pointers; the
m72/m73 sampler signature (QMD ACTIVE then freed, FECS unloads exactly at
dispatch, no fault) is consistent with the engine context restore failing on
the empty image. gsp_phys_rmcall_gr_r1_first=1 sends R1 before F2 (default 0 =
legacy order). Post-mortem now also reads CWD_FS (0x405b00).
