Remapping Copilot key triggers IME language switch (Maybe Shift key conflict) (rime/weasel)

[draftman9]

I noticed that when using this script, the remapped Copilot key also triggers the Windows language switch (e.g., toggling between Chinese and English) of Rime/Weasel.

Thanks a lot!

There is a bug where pressing the remapped Copilot key triggers the Windows IME language switch (e.g., Chinese/English toggle).

Cause:
The script only intercepts F23. The physical LShift and LWin are still sent to the OS. Even though the script sends {LShift Up}, the OS still registers the physical Shift release when the user lifts their finger, which Windows interprets as a standalone Shift press, triggering the IME.

To fix this, the script needs to intercept LWin and LShift at the hook level alongside F23, rather than just sending virtual Up strokes.
