Run GitHub Copilot CLI in headless mode with the Copilot SDK

I recently updated the FlightLog app ✈️ (built with the GitHub Copilot SDK and Azure Cosmos DB) to use the GitHub Copilot CLI in headless mode – the CLI runs as a separate process, and the app connects to it over TCP.

By default, the SDK spawns the Copilot CLI inside your app process. But it also lets you point to an external CLI running anywhere — a separate server, a sidecar, another container 📦

The instructions have been updated to use Docker Compose 🐳 to start the entire solution with a single command 🚀

Try it out, and let me know how it goes!
