A library addon placeholder for a Tree Assets Browser. The only file is an auto-generated compiler metadata file, so there is no runtime code or UI here.
An editor asset browser for s&box that shows project, engine and library files in a tree and icon grid, with create, rename, move, delete, drag and search. It also browses cloud packages, loads thumbnails, and can open package pages in the system browser. The code wires up UI panels, persists panel layout and expanded state via ProjectCookie, watches the filesystem, and integrates with AssetSystem for asset operations and reference rewrites.
