docs: point at the relocated workspace guide

The workspace guide moved out of the unversioned root into
cce-compositor/WORKSPACE.md, so this crate late reference now names that path
directly instead of ../CLAUDE.md, which is a bare pointer and no longer holds
the layout/multi-repo/build content this line promises.

 The entire app is **one file: `src/main.rs`** (~2200 lines) — a `DataEditorApp` struct
 implementing `cce_ui::engine::Application`, run by `cce_ui::engine::run::<DataEditorApp>()`.
