Use Outlines from .txt to replace strictValidation

https://github.com/dottxt-ai/outlines

Essentially, why would you need a `strictValidation` parameter when you can literally enforce it?

Outlines enables exactly that! The output can be clearly defined with a JSON schema or Pydantic model, or even RegEx!

Running sentiment analysis and just want either 'Positive' or 'Negative'? Easy! Just create a tuple with the possible outputs.

Start by locating the strictValidation parameter and the output-validation entry points in the TypeScript repository. Review how the toolkit currently handles sentiment outputs, then determine whether JSON schemas, Pydantic models, regular expressions, and tuples can replace the parameter; done means the proposed constraints are supported and documented with tests.
