[IDEA] Support Openrouter API Provider Routing

[tardigrde]

Describe the feature

Please evaluate supporting Openrouter's provider routing to allow user's more privacy-preserving model selection.

Use Case

Fot those who can't run a local model, but still want to have privacy, Openrouter keeps track of which providers retain data and/or train on user inputs, see docs.
Using provider routing would be 1 way to configure private providers/models without having to have a GPU at home.

Proposed Solution

IMO this is just static data that the user can enter via an interface before using the model.
