 * Ralph Hook
 *
 * Self-referential work loop that continues until cancelled via /oh-my-claudecode:cancel.

 *
 * Enhanced with PRD (Product Requirements Document) support for structured task tracking.
 * When a prd.json exists, completion is based on all stories having passes: true.
 *
 * Ported from oh-my-opencode's ralph hook.
