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.

 This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
 
 > This is the `cce-ui` crate. It lives inside the larger **`cce` Cargo workspace** — read the
-> workspace-root `../CLAUDE.md` first for the multi-repo layout, the standalone-build rule (no
-> `[workspace.dependencies]`), the KDL config system, and the Unix-socket IPC convention. This
-> file covers only what is specific to `cce-ui`.
