chore(copilot): sync load_slide_layout into the tool catalog

The file agent's slide-layout loader (Go-executed, never run by Sim) was
added to the mothership catalog but never synced here, so its transcript
row fell back to a humanized title. Sync the catalog entry, hide the row
like load_skill, and keep a fallback title for history.
