Fixes clipboard pasting on Wayland compositors (especially Unity) where
wtype fails with "Compositor does not support the virtual keyboard protocol".
Changes:
1. **ydotool 0.1.x compatibility**: Use key name syntax ("ctrl+v") instead
of scan codes ("29:1 47:1 47:0 29:0"). The key name syntax works on
both ydotool 0.1.x (Ubuntu packages) and 1.x versions.
2. **Prioritize ydotool on Wayland**: When no target window ID is available,
prefer ydotool over xdotool. xdotool reports success but can't reliably
paste without window targeting on Wayland.
3. **Improved terminal detection**: Add fallbacks for detecting terminal
emulators on Wayland where window class is unavailable:
- Check window title for terminal patterns
- Check process name of the window (most reliable)
This ensures terminals receive Ctrl+Shift+V instead of Ctrl+V.
Tested on Ubuntu 24.04 with Unity/Wayland compositor and wezterm.
