Add Windows 11 25H2 support with anti-DirectFlip overlay

[DeDuplicate]

Summary

• Add Windows 11 25H2 (build 26200+) support with updated AOB patterns and COverlayContext hooks
• Fix per-monitor LUT identification on 25H2 (DeviceClipBox at offset 0x7698 as float)
• Add anti-DirectFlip overlay to prevent games from bypassing the LUT filter via DirectFlip/MPO

Details

25H2 Hook Changes

• New AOB patterns for COverlayContext::Present, IsCandidateDirectFlipCompatible, and OverlaysEnabled
• 25H2 Present hook path: texture obtained via overlaySwapChain vtable chain instead of swap chain
• DeviceClipBox moved to offset 0x7698 from realObj (stored as float, not int)

Anti-DirectFlip Overlay

• On 25H2, IsCandidateDirectFlipCompatible is never called, so hooking it cannot prevent DirectFlip
• A persistent, nearly-invisible (alpha=1/255), click-through (WS_EX_TRANSPARENT), topmost window forces DWM to always composite
• Ensures the LUT filter stays active even when fullscreen games take focus

Test plan

• Tested on Windows 11 25H2 build 26200 with dual 2560x1440 monitors
• LUT applies only to the configured monitor
• LUT persists when fullscreen games (Call of Duty) take focus
• HDR/SDR backbuffer format detection works correctly
• Disable/re-apply cycle works without crashes
