/**
 * Freight e2e launcher — one command, no manual steps:
 *
 *   node e2e/freight/scripts/e2e.mjs <up|run|open|ci|down> [cypress args...]
 *
 * - run/open/ci auto-start the docker stack (build + wait healthy) if it
 *   isn't already running, then launch Cypress pointed at the right ports.
 * - Host ports default to 3101/5373/5383/5533/9310/9311; any default that is
 *   busy is replaced by the next free port. Chosen ports are written to
 *   e2e/freight/.e2e-ports.json (gitignored) and reused while the stack is
 *   up, so cypress and compose always agree.
 * - Extra args are forwarded to Cypress: `pnpm e2e:freight:run --spec ...`.
 *
 * No dependencies — plain Node, spawns `docker compose` and `pnpm`.
