- Use DirectInput8Create() instead of dynamic dinput.dll loading
- Switch to LPDIRECTINPUT8 / LPDIRECTINPUTDEVICE8 types and DI8 macros
- Replace custom MYDATA data format with c_dfDIMouse2 (8-button support)
- Use DIMOUSESTATE2 in GetDeviceState (correct size, 8 buttons)
- Add MOUSE5 button mapping via DIMOFS_BUTTON4
- Link against dinput8.lib; define required GUIDs inline to avoid dxguid.lib conflicts
- Fix .gitignore: remove Win32/ pattern that was shadowing code/win32/ source dir
