//! Conversation history compaction — shared selection/assembly logic for compacting
//! prior conversation turns into a summary.
//!
//! Everything here is generic over [`CompactionItem`](crate::CompactionItem)
//! / [`CompactionItemBuilder`](crate::CompactionItemBuilder) or pure
//! string/text manipulation. Harness-bound extraction (Kigi chat's
//! `KigiConversation` traversal, `ChatCompletionRequest` user-message
//! extraction, `KigiMessage` assembly) stays in the harness crate.
