v4.0.5-beta.12

Fixed

• Wrong colors on external monitors (third attempt) — removed the 8-bit pixel format conversion (copyTo8BitBGRA) that was corrupting colors on some monitors. The raw CGImage from ScreenCaptureKit is now passed through directly and AppKit handles color management natively, matching how other screenshot tools (e.g. Shottr) work.
• Editor cursor previews not showing — loupe follow, pencil/marker circle, stamp preview, and other cursor overlays were broken in the editor window since beta 9. A window-snap cooldown flag was blocking mouseMoved events.
