"""Prompt pipeline for the streaming server.

* :mod:`providers` — LLM backend abstraction + built-in adapters
* :mod:`enhancer` — provider-agnostic enhance / auto-extend / rewrite
  operations on top of the provider layer

All of this is optional; the streaming server runs fine without it
(PR 7.5's skeleton never invokes the enhancer). When the operator
enables ``ServeConfig.streaming.prompt.enabled``, the server routes
each ``session_init_v2`` curated prompt through ``enhance`` before the
first segment.
