feat: Raycast Extension

[JReinhold]

I would love a Raycast Extension for npmx. I use Raycast for everything throughout my day, and the extension I use the most is the npm extension to search for and look up packages:

https://www.raycast.com/mrmartineau/search-npm

But npmx has more valuable information, like package size, vulnerabilities, etc. that could be added directly into the Raycast extension's UI, to make it even more useful and ready-at-your-fingertips.

It would at minimum require an API for searching and getting package information, and I'm not sure we have the latter yet, but I could be wrong?
