[Feature]: TimeOut setting for Steps

### What would you like?

A TimeOut setting for Steps to fail the execution after a configured Duration in case downstream service does not response within that timeframe.

### Possible Implementation

Provide as StepConfig

### Is this a breaking change?

No

### Does this require an RFC?

No

### Additional Context

_No response_

Start by locating StepConfig and the step execution path in this Java SDK, then inspect how downstream service responses are handled. Define the timeout behavior around the configured Duration and verify that execution fails when the response exceeds it, using the repository's existing tests if available.
