• Introduces weco/constants.py with DEFAULT_API_TIMEOUT and replaces hardcoded API timeouts.
• Adds a --eval-timeout CLI argument and propagates it through execute_optimization.

• The docstring for run_evaluation should be updated to describe the new timeout parameter and its behavior.

def run_evaluation(eval_command: str, timeout: int | None = None) -> str:

weco/utils.py:132

• New timeout logic in run_evaluation should have corresponding unit tests to verify both normal execution and timeout behavior.

        result = subprocess.run(eval_command, shell=True, capture_output=True, text=True, check=False, timeout=timeout)

Looks good to me!

Would this require any changes to the onboarding copilot? Probably not since we would use the default value for eval-timeout which allows a unlimited time for the eval script's execution.

If this is the case, then feel free to merge @dexhunter

yes, timeout=None by default (unlimited)
