Development Flow in AI Studio CLI

For most artifact work, do these steps:

1. Inspect the project layout and the relevant files.
2. Run aistudio --help and aistudio <command> --help for commands you haven't used in the current context.
3. Don't hand edit the JSON files.
4. Create or modify local artifacts.
5. Run the matching validate-* command.
6. For workflows, run do-prettify-workflow after structural edits, then validate-workflow.
7. For material workflow edits, run the workflow test sync loop.
8. For material app edits with a top-level agent container, run the app test sync loop.
9. Save, publish, unpublish, or delete remote state only when explicitly requested.
