Add configurable timeout for Claude Code execution

Features added:
- Added --timeout/-t option to set execution timeout in minutes
- Default timeout increased from 10 to 15 minutes
- Validation: timeout must be 1-120 minutes
- Shows timeout in execution start message

Usage examples:
- ralph --monitor                    # 15-minute default timeout
- ralph --monitor --timeout 30      # 30-minute timeout for complex tasks
- ralph --verbose --timeout 5       # 5-minute timeout with progress logs

Benefits:
- Prevents hanging on very complex tasks requiring >15 minutes
- Allows shorter timeouts for simpler tasks to fail faster
- User can adjust based on their specific project complexity
- Clear feedback about configured timeout in logs
