Siddhant Rai 2a3f0e455a feat: condition node functionality with CEL evaluation in Workflows (#2280)
* feat: add condition node functionality with CEL evaluation

- Introduced ConditionNode to support conditional branching in workflows.
- Implemented CEL evaluation for state updates and condition expressions.
- Updated WorkflowEngine to handle condition nodes and their execution logic.
- Enhanced validation for workflows to ensure condition nodes have at least two outgoing edges and valid expressions.
- Modified frontend components to support new condition node type and its configuration.
- Added necessary types and interfaces for condition cases and state operations.
- Updated requirements to include cel-python for expression evaluation.

* mini-fixes

* feat(workflow): improve UX
