docs: update README license to Paperclip Labs, Inc (PAPA-437) (#6804)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The repository README closes with a license/copyright line that
downstream readers use to identify the legal entity behind the project
> - The line currently reads "MIT © 2026 Paperclip", which omits the
formal corporate name
> - The legal entity is "Paperclip Labs, Inc"; the README should reflect
that for accuracy
> - This pull request updates the README footer to "MIT © 2026 Paperclip
Labs, Inc"
> - The benefit is correct attribution of the MIT license to the actual
legal entity

## What Changed

- Updated `README.md` license line from "MIT © 2026 Paperclip" to "MIT ©
2026 Paperclip Labs, Inc"
