/**
 * Step: verify — End-to-end health check of the full installation.
 * Replaces 09-verify.sh
 *
 * Supports the EJClaw service stack:
 *   - ejclaw (Claude Code) — always checked
 *   - ejclaw-codex (Codex) — checked when .env.codex exists
 *   - ejclaw-review (Codex Review) — checked when .env.codex-review exists
 *
 * Uses better-sqlite3 directly (no sqlite3 CLI), platform-aware service checks.
