chore: drop MIT license and open-source framing

Project is now private; remove LICENSE file, README license
section, and "MIT · MMXXVI" footer tags. Root package.json
license set to UNLICENSED.

 ## Cost & limits
 
 Each turn costs roughly **\$0.15–0.25** in API fees with the recommended model trio. A 30-turn session is **\~\$5–8**. There is no rate limiting or auth out of the box — if you make your deployment public, your bill will reflect that. Add limits before sharing widely.
