Description
-----------

Backend abstraction.

Every leaf has one or more backends. A backend is the thing that actually
talks to a supported fluids product or service. Tools are LLM-facing. Backends are
implementation-facing.

A backend implements only the operations its product supports. Unsupported
operations raise `BackendUnavailable` so the typed-error guard converts them
to a clean error code instead of a 500 error code.
