/**
 * dev-runtime.mjs — starts the skills runtime with .env loaded.
 *
 * Loads .env from the repo root, then spawns the openhuman-core binary
 * with all env vars forwarded so skills can read BACKEND_URL, JWT_TOKEN, etc.
 *
 * Usage:
 *   node scripts/dev-runtime.mjs
 *   node scripts/dev-runtime.mjs --port 7799
