Type Alias BoxPromptService 

pub type BoxPromptService = BoxCloneService<PromptRequest, GetPromptResult, Infallible>;

A boxed, cloneable prompt service with Error = Infallible.

This is the service type used internally after applying middleware layers. It wraps any Service<PromptRequest> implementation so that the prompt handler can consume it without knowing the concrete middleware stack.
