// Shared column projections for queries against the messages_with_parts view.
// All sites that read the full Message wire shape for route responses use
// MESSAGE_COLUMNS. The inference load path uses INFERENCE_MESSAGE_COLUMNS —
// it adds reasoning_parts and model (per-turn attribution, used to label prior
// turns when a chat mixes models) but omits the compaction-display fields
// (summary, tail_start_id, compacted_at) that only the UI needs.
