Field meanings

• Family — provider family (e.g. openai, anthropic, local).
• Default model — what the provider uses if no --model is passed.
• API key env — the environment variable that holds credentials. (optional) providers run without one (typically self-hosted).
• Model env — overrides the default model per-process.
• Discovery — yes if the provider can list available models programmatically.
• Self-model — yes if the provider manages its own model selection (env vars / local defaults), so passing a tier model name is wrong.
