Build a creative workbench with Muse Spaces

@loi_jinli says that after Meta added Spaces to Muse, he stood up four workbenches: a free-quota radar, an AI video workflow, a creator studio, and a trending-topics board. The steps: first have the system report the cloud setup; set rules for the agent so that before it sends email, posts, or pays, it shows the recipient and the draft for confirmation; use one real topic to build a topic library and check that the record is still there; then hand repeated queries to a scheduled job and confirm that it actually updates. Get a manual run right once, then automate. What Spaces can do, and the "free quota," should be checked against the actual product and have not been independently verified.
