//! Pure rendering of a compacted segment into self-contained markdown, aligned
//! with the Python compaction implementation (`render_segment_to_markdown` /
//! `compute_turn_stats`; INDEX built incrementally via [`INDEX_HEADER`] +
//! [`render_index_row`]). No I/O.
//! Not byte-identical — the data models differ (Python `Turn`/channels vs our
//! [`ConversationItem`]) — but headers, sections, detail levels, and INDEX
//! columns match.
