//! Streaming Tool Calls
//!
//! Provides a streaming agent that emits LLM text token by token and exposes
//! tool-call state.
//!
//! B8 (v0.22.4): [`sse`] maps [`AgentStreamEvent`] to Server-Sent Events
//! frames; the `sse-server` feature serves them at `text/event-stream` over
//! axum 0.7 (`POST|GET /agent/stream`).
