/**
 * Assistant checkpoint payload extractor for Iranti's shared checkpoint system.
 *
 * Reads `<iranti:project:*>` structured tags from an assistant response and
 * assembles them into an AssistantCheckpointPayload. The payload captures the
 * current step, next step, open risks, recent outputs, recent actions, and
 * file changes that the Attendant should persist to the shared checkpoint.
 *
 * This module is intentionally read-only — it extracts and normalizes, it
 * does not write to the database. The caller (Attendant post-response scan)
 * owns the write.
 *
 * Key exports:
 *   - extractAssistantCheckpointPayload()  — parse a response string into a checkpoint payload
 *   - AssistantCheckpointPayload           — the structured payload type
