feat(server): enhance script execution and workflow management

- Introduced compileWorkflowScripts function to parse and validate workflow scripts, supporting both linear and DAG execution modes.
- Added runLinearSteps and runDagSteps functions for executing compiled workflows based on their structure.
- Updated createRegistry function to utilize the new workflow compilation and execution logic.
- Enhanced script sandbox with meta extraction and instantiation capabilities for better script management.
- Improved API endpoints to return script metadata and handle errors more effectively.
- Removed deprecated scripts and updated workflows to reflect new structure and functionality.
