Custom plugins per project

I wonder if it would be possible/practical to allow a project to have its own plugins for the CLI. For example, a custom generator.

The CLI could look at the project's "unthink" block in the package.json and load referenced plugins there?

Start by reviewing the CLI entry point and how it currently reads a project's package.json. Clarify the plugin contract, loading rules, and custom-generator behavior before implementation; the issue does not yet define what supported plugins or completion criteria should look like.
