/**
 * upgrade-test.mjs — OpenClaw Upgrade Compatibility Test Suite
 *
 * Checks:
 *  1. AGENTS compatibility — all sections present
 *  2. GOVERNANCE compatibility — all sections present, state machine valid
 *  3. PORTFOLIO compatibility — all sections present, project states valid
 *  4. Audit compatibility — all 4 audit scripts run without crash
 *  5. Template compatibility — all 7 templates are valid markdown
 *  6. Cross-ref integrity — no broken references between docs
 *  7. Version Contract compliance — required interfaces exist
 *
 * Usage:
 *   node scripts/upgrade-test.mjs
 *
 * Returns exit code 0 if all PASS, 1 if any FAIL.
