feat: Add Hugging Face as a provider

[gary149]

Add Hugging Face Inference Provider as remote engine.

Note: If I understand correctly, we'd need to be registered in token.js to be treated as a first-class provider (non-deletable)?
Btw feel free to take over on this (one cool thing is that free users get a few free messages to try out)

Awesome work, @gary149! We'd love to proceed with the merge and then apply a few minor adjustments. You're correct that we're deprecating engine-management-extension and moving the provider to be part of the app so it can be treated as first-class provider.
