Subject: [PATCH] Enhance Workflow Execution with Notification and Decision
 Node Features

- Added support for notification nodes in the workflow execution process, allowing users to send notifications with customizable messages and recipients.
- Implemented decision and gateway nodes to facilitate user interaction and automatic condition evaluation, enhancing workflow flexibility.
- Updated the execution logic to handle multiple paths based on user decisions or automatic evaluations, improving user experience during workflow execution.
- Enhanced the HTML content handling to support dynamic variable interpolation, allowing for more personalized content display in HTML nodes.
- Introduced debugging features for variable mapping and field conditions, aiding developers in understanding and troubleshooting workflow behavior.
