Add ydotool as a fallback option for direct text input and key
combinations on Linux, after wtype/dotool (Wayland) and xdotool (X11).
ydotool uses uinput and works on both Wayland and X11, making it a
useful alternative when other tools are unavailable.
Requirements:
- ydotool installed
- ydotoold daemon running
- User in input group with uinput permissions
