Added experimental mouse movement: click an accessible spot to walk there, or double-click to run. This feature is still in development, so you may encounter bugs.

What to test:
- Clicking to walk and double-clicking to run across different scenes.
- Choosing a new destination while moving.
- Navigating around obstacles, corners, and narrow passages.
- Switching to keyboard movement — this should cancel the current route.
If your character gets stuck or ignores a click, please tell us which scene it happened in and include a short video/photo if possible in our Discord channel: https://discord.gg/rJMnRYwFdV
