- Updated execution control methods (`PauseExecution`, `ResumeExecution`, `StopExecution`) to include error handling and database status updates for paused, running, and cancelled states.
- Introduced `ExecuteWithControl` method in the Executor interface to manage execution with pause/resume capabilities, allowing for better control during execution.
- Enhanced the `Execute` methods across different executors (DryRun, Sandbox, Standard) to support pre-generated execution IDs and control mechanisms.
- Improved error messages in the execution handling API to provide clearer feedback on execution status and errors.
- Added support for a new execution status `ExecPaused` in the execution model, enhancing the tracking of execution states.
- Introduced multiple executor modes (Standard, DryRun, Sandbox) to accommodate various use cases, enhancing flexibility in execution strategies.
- Updated DESIGN.md to reflect the new executor modes and their respective use cases, including detailed descriptions and configuration examples.
- Revised TECHNICAL.md to outline the new executor package structure, emphasizing the modular design for future enhancements.
- Enhanced the TODO.md to track the progress of executor mode implementations and related tasks.
- Removed outdated executor stub files and tests, streamlining the codebase for improved maintainability.
- Updated integration tests to utilize the new DryRun executor, ensuring comprehensive coverage of execution scenarios without real agent calls.
- Marked the Pool Implementation as complete in TODO.md, confirming all tasks are finished with comprehensive tests.
- Introduced a configurable worker pool with a priority queue for managing robot jobs, including graceful shutdown support.
- Enhanced the Executor with simulated execution delay and callback functionality for testing, tracking execution counts.
- Improved error handling in the pool's submission process and added methods for retrieving running and queued job counts.
- Updated tests to ensure robust functionality and performance of the pool and executor components.
