//! Conversation summarization — constants and helpers only.
//!
//! The summarization LLM call itself has moved to `crate::Agent::summarize`
//! so that all parameters (model, temperature, reasoning_effort, tools,
//! provider routing) are byte-identical to the agent's work loop.
//! This module retains the constants and helpers used by `Session::apply_summary`.
