Overview
Add a timeout field to the DAG configuration to specify the maximum time allowed for a task.

Requirements
When a timeout occurs:

• Mark the entire DAG as errored
• Cancel all steps currently in execution

Implementation

• Modify the DAG configuration schema to include the new timeout field
• Update scheduler logic

Example DAG configuration

timeout: 3600  # Timeout in seconds (1 hour)
steps:
  - command: some long work

Testing

• Add unit tests for the timeout functionality
• Create integration tests with DAGs that trigger timeouts
• Ensure proper error handling and logging of timeout events
