python/peps — reverse-engineered prompt

I want a local version of the Python Enhancement Proposals site working from this repo. It should take the PEP files written in reStructuredText, render them into clean HTML, and put the built site in a build folder so I can browse it locally. Please make sure the PEP index is generated automatically from the metadata in the PEP files, and that links use the normal zero padded format like pep 0008 while still supporting short redirects like pep 8.

I also want the basic checks in place so broken formatting, rendering problems, and obvious spelling or lint issues get caught before changes are committed. If there are API data files that are supposed to be published with the site, include those in the local build too.

Basically, get this repo into a state where someone can install what it needs, run one build command, and preview the full PEP website locally. You can look up current docs online if you need to.
