🤖 Generated by Copilot at 418ff82

Refactored and improved the inspector's components, hooks, and data layer modules to handle asset paths more consistently and reliably, and to support hiding entities from the hierarchy view. Added a new method and message type to the data layer protocol to retrieve the project path. Updated the README and the CSS files accordingly.
