feat: add Nuvio Plugin Support

[autovalue]

Separating #2 into a different issue.

It would be nice if the framework could be used to write Nuvio providers.

For those unaware, Nuvio allows you to use self-contained singular javascript files that can be executed by the local device (primarily using QuickJS) without needing to host or proxy it on a server (severely reducing the barrier to entry for using providers), as well as support instances where the server hosting the framework is a free instance, and might easily terminate if they notice too many requests being proxied out of it.

An example compiled provider is available here.

Okay so I read myself through the whole thing and it should be possible.

Note

However since TS to JS to async/await free JS is not an overnight thing to do.... To get nuvio plugin support to the OMSS framework will definitely take some time.
Expected resolution time: mid August 2026 (might take longer, and this is not P0.... although I know it would be kinda cool).

I already have a working version that compiles the provider into a single script (and unraveling the proxy URL from the source and subtitles), I can contribute it back into a public fork in due course, in case it's something that's useful - but that's not the main focus of this PR.

Feel free to share the file/s and/or open a PR.
But like stated above, it might take some time for the whole thing to go through.

Also I noted that there is no SSOT to the whole JSON spec so it's gonna be a little hard to follow the "spec" if there isn't really one..... or i just couldn't find it rn.
