Add agent skills support /google-styleguide

[rodydavis]

Adds agents skills support for the style guides for various languages. Created as a single skill since most repos have a variety of languages included.

• generated from source
• renders all templates
• adds top level skills directory
• adds python script to keep it always up to date

Happy to move it to https://github.com/google/skills if needed.

if we land it in this repo, we should at least use symlinks instead of duplicating .md files.

somewhere you should document why you need/want to transform the HTML into MD. maybe in the Python script that does the transformation.

we should add a GH action that runs the script in a "check" or "diff" mode so that it fires on every PR to make sure things stay in sync.

I don't have a strong opinion on putting it in here vs google/skills. if there's guidance in using that project as a single source of Google skills, then that makes sense.

Done! This worked a lot better and tested installing skills with the symlinks and had no issues.

No longer doing a transform

Done and will run on every push

This repo would be ideal since it could stay in sync
