Could not determine Anthropic credential source

Error message

Could not determine Anthropic credential source

What it means

Anthropic equivalent of the OpenAI credential-source prompt: after selecting Anthropic as provider, a picker offers 'Use GitButler API' vs 'Bring your own key', and cancelling it (None result) raises this error before the model/API-key prompts run.

Solutions

1. Choose 'Use GitButler API' to skip key handling.
2. Or create an Anthropic key (console.anthropic.com), re-run, pick 'Bring your own key' and paste it.
3. Re-run `but config` AI setup to restart the flow.

match configure_ai(out).await {
    Err(e) if e.to_string().contains("Anthropic credential source") => { Ok(()) }
    other => other,
}

When it happens

Trigger: Selecting Anthropic in AI config, then aborting the 'Select Anthropic credential source' picker with Esc.

Common situations: User needs to create an Anthropic API key first; deciding between proxied and own key.
