Enhance Executor Stub Implementation and Update TODO.md

- Marked the Executor Stub Enhancement section in TODO.md as complete, detailing the enhancements made to the executor's functionality.
- Improved the Executor to simulate full execution with Job integration, including phase transitions and logging.
- Introduced a Config struct for customizable executor behavior, allowing for testing with callbacks and job integration control.
- Implemented phase-specific methods for modular execution, preparing for future real phase implementations.
- Added comprehensive tests for the executor, including smoke tests and verification of phase progression and job logs.
- Updated progress tracking in TODO.md to reflect the current status of the executor and integration testing.
