[Feature]: Set a "global" timeout for the entire workflow about stepci

Note: This may only be relevant and might want to be moved into the stepci/runner codebase.

Thank for starting the issue,
Keep in mind, you can already specify timeout in your CI/CD

@mishushakov Timing it out elsewhere isn't handling it gracefully with a proper resultset map about the failure and what occurred and at what step it failed/stalled at. That doesn't really solve the underlying issue.

Note: I'd be happy to sponsor someone to add this feature if anyone's down
