/**
 * Forgen — Compound Dashboard
 *
 * Provides a rich terminal overview of the compound knowledge system:
 * knowledge inventory, injection activity, lifecycle transitions,
 * session history, and hook health.
 *
 * Data is collected from:
 *   - ME_SOLUTIONS, ME_RULES, ME_BEHAVIOR (knowledge files)
 *   - MATCH_EVAL_LOG_PATH (injection/matching decisions)
 *   - STATE_DIR (hook-errors.json, last-extraction.json)
 *   - Solution frontmatter (lifecycle evidence fields)
