//! # Embacle — LLM Runners
//!
//! Standalone library providing pluggable [`LlmProvider`](types::LlmProvider)
//! implementations that delegate to CLI tools (Claude Code, Copilot, Cursor Agent,
//! `OpenCode`, Gemini, Codex, Goose, Cline, Continue, Warp, Kiro, Kilo Code), an HTTP API client
//! (OpenAI-compatible), and ACP (Copilot Headless) for LLM completions.
//!
//! CLI runners wrap a binary, build prompts from [`ChatMessage`](types::ChatMessage)
//! sequences, parse JSON output, and manage session continuity. The Copilot Headless
//! runner communicates via NDJSON-framed JSON-RPC with `copilot --acp`.
//!
//! Two companion binary crates build on this library:
//! - **`embacle-server`** — OpenAI-compatible REST API + MCP Streamable HTTP on a single port
//! - **`embacle-mcp`** — standalone MCP server over stdio or HTTP
//!
//! ## Progress feedback (AG-UI)
//!
//! With the `agui` feature enabled, the [`agui`] module exposes the
//! [AG-UI protocol](https://github.com/ag-ui-protocol/ag-ui) event vocabulary
//! plus an emitter trait so downstream runners, agent loops, and pipelines
//! can report run/step/tool/text progress to user-facing clients without
//! coupling to a specific transport.
