/**
 * PM2 ecosystem config — production process manager.
 *
 * Single fork (NOT cluster mode) because:
 *  - SqliteSessionStore is in-process: cluster workers wouldn't share sessions.
 *  - better-sqlite3 is synchronous and not designed for multi-process writes.
 * If you ever need horizontal scaling, swap the session store for a shared
 * backend (Redis) first, then enable cluster mode.
 *
 * Usage:
 *   pm2 start ecosystem.config.cjs --env production
 *   pm2 save && pm2 startup    # auto-start on boot
 *   pm2 logs klonkt
