feat: enhance task runner with task status updates and process comman…

…d execution

- Added a task status update to 'processing' at the start of the Run method in runner.go, improving task tracking.
- Removed redundant task status update from the end of the Run method to streamline the execution flow.
- Updated command execution in process.go to use 'bash' instead of 'sh' for better compatibility across environments.
