feat(hyprland): add touchpad state indicator to waybar

The $mod+F9 toggle and the toggle-touchpad / touchpad-auto scripts already worked, but the scripts lived only in ~/.local/bin and were never committed, and there was no way to see the touchpad's state at a glance.

I committed both scripts into the repo so stow installs them, and added a waybar indicator: a waybar-touchpad status script and a custom/touchpad module that shows a mouse glyph when the touchpad is on and a mouse-off glyph (in the dupre orange) when it's off. The scripts signal the module with pkill -RTMIN+9 waybar after each state change, so the icon updates the moment the touchpad toggles. touchpad-auto now runs at login via exec-once.

The waybar-touchpad script has unit tests under tests/waybar-touchpad/ covering the enabled, disabled, and missing-state-file cases.
