Give a summary of what the PR does, explaining any non-trivial design decisions

Add VSCode based on https://github.com/gitpod-io/openvscode-server, so we can quickly pop up an editor on UI to play around with files and download them properly (the current download zip in UI doesn't work too well)

This is finally ready for review!

Really rough mock up. Would like to get Paul on this once he's back

[xingyaoww]

Implemented! Ready for another look:

[rbren]

This button should be disabled or invisible until the runtime is ready

[rbren]

The toast is a little frustrating. It's not enough time for me to read, and long enough that it feels like VS Code is taking a long time.

I'd suggest putting a message into the chat window saying:

You opened VS Code. Please inform the agent of any changes you made to the workspace or environment. To avoid conflicts, it's best to pause the agent before making any changes.

@rbren

Now the button is gray out & not working when the runtime is not initialized

And turn blue (our setting modal blue, not vscode blue) when the agent / runtime is ready:

And new messages will be added to VSCode (I've been thinking if we need to set a different color / style for this message so user know this is not from the agent)

@xingyaoww sorry for the delay on review! But I'm getting this error when trying to run:

    raise LLMMalformedActionError(
openhands.core.exceptions.LLMMalformedActionError: action={'id': 5, 'timestamp': '2024-11-12T12:01:39.428213', 'source': 'user', 'message': 'do a flip', 'action': 'message', 'args': {'content': 'do a flip', 'image_urls': [], 'wait_for_response': False}} has the wrong arguments: MessageAction.__init__() got an unexpected keyword argument 'image_urls

maybe need to rebase?
