Vouch Request: Improve OpenShell developer onboarding documentation

[mia03ther]

What do you want to work on?

I would like to contribute improvements to OpenShell's developer onboarding experience, especially around documentation, examples, and setup guidance for new contributors and AI agent developers.

I am interested in helping make OpenShell easier to understand and use by improving quickstart materials, clarifying workflows, and adding examples where needed.

Why this change?

I am interested in AI agent infrastructure and developer tools. While exploring OpenShell, I noticed that clear onboarding materials are important for developers who are new to the project.

I would like to contribute by improving documentation and examples that help more developers quickly understand OpenShell and start building with it.
