"""First-party LLM provider construction data.

One row per provider Tracer ships native clients for. The tool-calling, reasoning,
and LiteLLM builders read this table instead of repeating a per-provider branch, so
adding a first-party provider is a single row rather than an edit in four dispatchers.
