aaronpowell/copilot-sdk-web-app ? reverse-engineered prompt

Build me a full stack web app where I can sign in with GitHub and chat with Copilot in the browser.

I want a simple chat experience with a sidebar for past conversations, the ability to open an old session and keep talking, and a way to delete sessions I don’t want anymore. It should also let me pick from the available Copilot models before sending messages.

Please wire up the backend so each signed in user gets their own Copilot session, and keep the chat history saved so it survives refreshes. Use a clean React frontend with a nice chat layout, and an ASP.NET Core API for the auth, chat, sessions, and model endpoints. If anything needs current setup details, look up the latest docs online.

Also make local development easy with Aspire, including whatever is needed to run the frontend, server, and dashboard together.
