Implement Paper Auto

This one takes a research paper URL and builds a complete marimo notebook implementation without asking you for input. It pulls structured paper content from AlphaXiv, then makes its own call on what concept to showcase. The real philosophy here is storytelling over completeness. Instead of trying to replicate every benchmark, it picks one core idea and builds a minimal, runnable example with a chart or two and maybe some interactive controls. No toy datasets, no endless scrolling. It's opinionated about hiding code by default and surfacing the interactive bits first. Useful when you want to quickly explore a paper's key insight rather than read through pages of methodology.
