[srijanpatel]

This pull request includes changes to the backend/pyspur/api/workflow_run.py file to improve the handling of node outputs in workflow runs. The primary focus is on refactoring the code to use a new helper function for mapping node titles to their outputs.

Refactoring and code simplification:

• Added import for BaseNodeOutput in backend/pyspur/api/workflow_run.py to support the new helper function.
• Introduced the get_node_title_output_map function to create a dictionary mapping node titles to their outputs.
• Updated async def run_workflow_blocking_v2 to use the new get_node_title_output_map function, simplifying the code for creating the outputs dictionary. [1] [2]
• Modified async def run_workflow_blocking to use the new helper function for setting the outputs.
• Updated async def run_workflow_task and _handle_pause_exception to use the get_node_title_output_map function, ensuring consistency in how outputs are handled. [1] [2]
