Extension development for code-server compatibility

[diraneyya]

Hello everyone (and mostly @code-asher).

I am in the process of creating a PR for the vscode extension for Evidence, an awesome reporting tool, here evidence-dev/evidence#3201

The issue I am facing is that depending on whether the user is using vscode locally or via code-server, providing a seamless experience requires different measure.

Namely, unlike in native vscode, port forwarding works entirely differently in code-server. This is an important distinction for someone running the extension on a remote machine using code-server from Coder.

Is there a way to detect that we are running inside of a code-server, as compared to vscode natively, and what is the recommended way to interact with the auto port forwarding feature. Namely, when the user does not specify a preferred port or when the port is occupied and the command ends up running on a different port. This is a time where probing the auto forwarder asking for the actual port can be of great use.

Any level of information or a hint into where to look would be great.

Kind regards,
Orwa.
