/**
 * Cross-platform wrapper that forwards arguments to whichever Docker Compose
 * implementation is available on the host:
 *
 *   1. `docker compose` (Compose V2 plugin, shipped with modern Docker Desktop)
 *   2. `docker-compose`  (legacy standalone V1 binary)
 *
 * This exists because contributors run a mix of both and neither is guaranteed
 * to be installed. The wrapper prefers V2 when available and transparently
 * falls back to V1, so npm scripts like `test:docker:up` work everywhere.
