//! Agent module providing middleware, tool-calling agents, structured output support,
//! and output parsers for converting raw LLM text into structured agent actions.
//!
//! Output parsers for common formats:
//! - [`ReActOutputParser`] — parses `Thought: / Action: / Action Input:` and `Final Answer:` blocks
//! - [`JsonOutputParser`] — parses `{"action": "tool", "action_input": {...}}` JSON
//! - [`XmlOutputParser`] — parses `<tool>name</tool><tool_input>input</tool_input>` XML
//! - [`ToolCallOutputParser`] — converts structured tool-call objects from chat models
//!
//! Mirrors Python `langchain.agents`.
