feat: fetch openrouter supported models in goose configure

[The-Best-Codes]

Before:

You have to type out a model manually.

┌   goose-configure
│
◇  What would you like to configure?
│  Configure Providers
│
◇  Which model provider should we use?
│  OpenRouter
│
●  OPENROUTER_API_KEY is already configured
│
◇  Would you like to update this value?
│  Yes
│
◇  Enter new value for OPENROUTER_API_KEY
│  [REDACTED]
│
◇  Model fetch complete
│
◆  Enter a model from that provider:
│  anthropic/claude-3.5-sonnet (default)
└

After:

Goose CLI will automatically fetch the list of models that support tool use from OpenRouter when you configure it as a provider:

┌   goose-configure
│
◇  What would you like to configure?
│  Configure Providers
│
◇  Which model provider should we use?
│  OpenRouter
│
●  OPENROUTER_API_KEY is already configured
│
◇  Would you like to update this value?
│  Yes
│
◇  Enter new value for OPENROUTER_API_KEY
│  [REDACTED]
│
◇  Model fetch complete
│
◆  Select a model:
│
│  ● ai21/jamba-1.6-large
│  ○ ai21/jamba-1.6-mini
│  ○ amazon/nova-lite-v1
│  ○ amazon/nova-micro-v1
│  ○ amazon/nova-pro-v1
│  ○ anthropic/claude-3-haiku
...

Ready for review!

very nice - I don't have access to manually test open router - any chance you can add a small recording showing it in action?

Also - where is fetch_supported_models_async called from? I must be missing some context

[The-Best-Codes]

@michaelneale The fetch_supported_models_async function is a public function. It was added to base.rs in a previous PR. Providers can optionally include that function to enable supported model fetching.

goose/crates/goose/src/providers/base.rs

Lines 251 to 253 in 67664a2

	async fn fetch_supported_models_async(&self) -> Result<Option<Vec<String>>, ProviderError> {
	Ok(None)
	}

It gets called in configure.rs:

goose/crates/goose-cli/src/commands/configure.rs

Lines 330 to 338 in 67664a2

	// Attempt to fetch supported models for this provider
	let spin = spinner();
	spin.start("Attempting to fetch supported models...");
	let models_res = {
	let temp_model_config = goose::model::ModelConfig::new(provider_meta.default_model.clone());
	let temp_provider = create(provider_name, temp_model_config)?;
	temp_provider.fetch_supported_models_async().await
	};
	spin.stop(style("Model fetch complete").green());

[michaelneale]

nice isolated change, will help with experience with open router

[michaelneale]

@The-Best-Codes merged - wonder if future enhancement is to have some UI that lets people find.. as there is a lot! (but no idea what that would look like)

[The-Best-Codes]

@michaelneale Awesome!

have some UI that lets people find

Do you mean in Goose desktop or a TUI? In the terminal, maybe type to search the list of models?
