What does this PR do?

Today opencode displays a static list from models.dev of 3 models in lmstudio. Since LM Studio is intended to be self-hosted, it made no sense for the list to be static. Even though there is the possibility to add models manually via config files, still, it's too much hassle for something that should come out of the box.
This PR adds the ability to load the model list from LM Studio dynamically.

How did you verify your code works?

1. Run the project once in branch dev to assert everything works and I don't chase unrelated changes later.
2. Did my changes
3. Build it
4. Run the newly built version
5. Assert that the list of models that appears on the provider LM Studio is truthful with the ones provided by LM Studio's API endpoint
