Allow users to see their own print statements in the logs

(Also set indent-width = 2 matching current indentation so that code doesn't get reformatted)

Pull request overview

This PR aims to make user code print() output visible in server logs in near real-time by streaming subprocess stdout/stderr line-by-line into the JSON logger, and adds a Ruff indentation setting to avoid auto-reformatting.

Changes:

• Add Ruff indentation configuration to match the repo’s 2-space Python indentation.
• Log subprocess stdout/stderr lines as they arrive (instead of waiting for process completion).
• Refactor run_command to drain stdout/stderr concurrently via background threads and still return the last stdout line on success.

There was the idea to limit the number of line to something finite. I can't find it here.
