I don't know if it's appropriate for your case, but devcontainer <https://devcontainer.community/awesome>, code-server, or Eclipse Theia are basically VSCode over http and will mimick the GitHub.dev experience. I'm guessing a lot of your heartburn was trying to get the graphical parts of Electron to operate inside docker but it's really not good at that

I did see the VSCode part, but it might interest you that the JetBrains products also have an rpc style development setup through Gateway, where the product runs effectively headless in the container and just sends the display commands to your local IDE to handle latency sensitive GUI operations
