docs(stacks-svelte): generate llms friendly docs from storybook content

[giamir]

SPARK-93

Attention: 2 vibe coded files are checked in as part of this PR

This PR introduces a script that analyze the content of the stacks-svelte source and related storybook docs and generates a llms.txt summarizing all that content in markdown easily digestible by LLMs.

The only package I could find out there to take storybook docs and make them LLMs friendly was this one. Unfortunately though the package support only storybook v7 and v8 and we are using v9. It also uses playwright under the hood.

Until there’s a more established package that supports converting Storybook docs to Markdown, I’ve opted to vibe code what we need in a very isolated tools folder. In general, I’m not in favor of checking in code generated by LLMs unless we fully understand it. However, for this specific use case, I think it’s acceptable — the script is unlikely to need ongoing maintenance, and even if it breaks, the only loss would be something primarily useful for LLMs.

How to test

• Check out this branch
• Run npm run storybook:build -w @stackoverflow/stacks-svelte
• Open packages/stacks-svelte/netlify/dist/llms.txt and check the generated markdown

We're finally on the cutting edge 🎉

100% agree. Seems like a wise, low-liability use of vibe coding.

I followed the PR instructions and llms.txt generated exactly as in the preview (besides **Generated:** 2025-10-21T20:08:03.165Z of course 🙂). Solid LGTM material!
