Type Alias BackendFactory 

pub type BackendFactory = Box<dyn Fn(String, &BackendConfig) -> Result<Box<dyn Backend>, BackendError> + Send + Sync>;

A closure that creates a concrete backend from its name and config.

This is the bridge between rite-runtime (which defines the registry) and rite-stdlib (which provides the concrete implementations). The CLI injects rite_stdlib::backend::create_backend as this closure.
