Refactor Structs for Consistency and Enhanced Readability

- Standardized field formatting in TriggerResult and Execution structs for improved code clarity.
- Added test cases in robot_test.go to ensure Robot can run with nil config and quota, verifying default behavior.
- Enhanced comments in the Goals struct to clarify task objectives and improve documentation consistency.
