pyrevitlabs/pyRevit ? reverse-engineered prompt

Build me a pyRevit style toolkit for Autodesk Revit that makes it easy to run custom Python tools right inside Revit.

I want a polished base app with a simple ribbon style interface, a way to organize and load extensions, and a clean place for reusable scripts and helpers. It should feel like a developer friendly environment for making small Revit automations fast, not a full blown separate app. Include the pieces needed for creating, packaging, and updating extensions, plus enough example tools so I can see how it works.

Make it practical for real Revit users, with clear commands, sensible defaults, and documentation in the repo for how to set it up and add new tools. If you need current Autodesk Revit or Python integration details, look them up online before wiring it up.
