Stop the title-screen from forcing the Windows cursor back into a small centered box while the Commonwealth Online overlay owns input. Changes:
- Intercept SetCursorPos and ClipCursor in the Fallout4.exe import table (IAT) and make them no-ops while the overlay owns the pointer.
- Hook MainMenu BSInputEventUser vtable cursor/mouse-move slots to consume events when custom menu input is captured.
- ReleaseMenuCursorConstraints(): clear constraints, unset forceOSCursorPos, expand cursor bounds to the full window, and clear OS ClipCursor. Re-assert each frame during AdvanceMovie.
- Add InstallCursorApiHooks() and wire it into PrismaUI init; add logging.
- Update changelog.md to document the fix. Binary compiled script and minor source formatting updated.
