Build me a simple TypeScript app that acts like an autonomous marketing assistant for TikTok.

I want to give it a goal in one place, add my API keys in a .env file, and then run it from the command line so it can figure out what kind of content to make, use the other services it needs, and return a Doublespeed review link when it is done. It should support a one time login step for Doublespeed, save the token locally, and then keep working from there. By default, it should leave everything as a draft for review, not post anything live unless I explicitly turn that on.

Please make the setup feel dead simple, with clear install and run steps, and include sensible defaults for the main settings near the top of the script so I can change the account and goal easily. If you need to check current API details, look them up online.
