feat: support granular context file setting

[sean-roberts]

🎉 Thanks for submitting a pull request! 🎉

Summary

Docs has been refactored to provide granular context data: https://github.com/netlify/docs/pull/4352 - this needs to be deployed before this CLI version goes out.

This update to the recipe for ai context introduces a few changes:

• dynamic lookup of the available consumers/clients, docs will tell us what clients we allow explicit path installation for.
• context files will be created in a granular fashion instead of a massive netlify-development.mdc file, it will put all of the context files assigned to the given tool into specific files. So if the consumer (e.g. windsurf) is assigned 5 different context files on the docs, we will add all five
• it moves the file naming, file truncation, and file download URLs to the configuration from docs
• we prefix all local files now with netlify-... given this, we've removed the explicit confirmation about overriding existing, non-netlify files.

All that to say, going forward, if we want to add a new consumer tool (like Sourcegraph's Amp) we just update the docs with the new consumer, assign the context files it will need, the path to put it in, etc. and this recipe will automatically pick it up without needing an update. The goal is that as we find more nuances to the consumer tools, their needs for files, etc. we can update those on the context hosting (docs) and we can move more quickly.

I don't know, @smnh will need to verify. Currently, this work is all wrapped in try/catch and will skip if any errors are thrown and, if it simply doesn't work, then it will also continue as it does without this logic.
