Add LLM support for doc sites

[jis3r]

Inspired by this post by Linear, and the fact that the official Svelte documentation also includes a link to an llm.txt file on each doc page, I’m wondering if this could be a nice addition to the project.

I know it's not currently part of the original shadcn/ui project, but I came across this PR, which seems to be heading in a similar direction.

In my opinion, it would be a great addition to the project and might be even more valuable for the Svelte ecosystem than for React/Next.js, as LLMs tend to perform worse when generating Svelte code in my experience.

Looking forward to hearing your thoughts on this! I’d also be happy to implement it if we decide to move forward with something like it. :)

I just saw that bits-ui also has the same functionality
