Brings the complete GV7 campaign: GSBackQueue SPSC record ring, draw/ transfer/PCRTC/vsync records with inline executors, the GSFrontState two-object front split, lockstep + pipelined back-thread modes (default Off), mid-frame MTGS-thread drain seams, back-thread affinity fix, and the Qt/Big Picture GSBackThreadMode settings UI. Conflict resolutions: - pcsx2/GS/GS.cpp: adjacent additions unioned (Android Tekken 5 Mali override + GV7 g_gs_front/GSParseTarget). GSAllocateWrappedMemory unioned semantically: keeps the iOS-safe HostSys::CreateSharedMemory routing AND drops the static fd so two wrapped allocations coexist (the GV7 two-object split runs two GSStates, each with a wrapped vm); CreateSharedMemory already unlinks/memfds the name and the iOS file-backed fallback O_EXCL-retries per-attempt paths, so coexisting allocations cannot collide. - GraphicsAdvancedSettingsTab.ui: take gsBackThreadMode tabstop; drop yaps2's stale "rov" tabstop (no such widget in either tree). - FullscreenUI_Settings.cpp: GS Back Thread setting inserted outside the ARMSX2 !__APPLE__ guard around exclusive fullscreen. Audit: ARMSX2 one-liners in GV7-rewritten files survived (GSClut CreateFeedbackTarget, GSState SaveTransferImages); ARMSX2's Merge()-path additions (RetroArch shader chain, FastMAD fallback) run post-drain on the vsync path, so no unaudited device seams. Gates on merged tree: recompiler_tests 1359/1359, gs_vertex_tests 21/21 (incl. new gs_backqueue suite), full build incl. armsx2-qt.
