"""Factory for building a rerank provider from :class:`RerankSettings`.

The ``provider`` field on :class:`RerankSettings` selects which concrete
implementation to build:

    - ``"deepinfra"``  → :class:`DeepInfraRerankProvider`
    - ``"vllm"``       → :class:`VllmRerankProvider`
    - ``"dashscope"``  → :class:`DashScopeRerankProvider`

Adding a new provider = one match arm here + one new file under
:mod:`everos.component.rerank`.
