feat: add create_root_span parameter to UiPathExecutionRuntime

[AAgnihotry]

Summary

Adds create_root_span parameter to UiPathExecutionRuntime to decouple logging context setup from root span creation.

Changes

• Added create_root_span parameter (default: True) to UiPathExecutionRuntime.__init__()
• When True: Creates root span with execution.id (existing behavior)
• When False: Sets up logging context only, no root span created
• Updated both execute() and stream() methods to respect this flag

Use Case

Enables evaluation runtime to avoid duplicate root spans while maintaining proper logging context:

• Evaluation runtime sets create_root_span=False
• Logging context is set up with execution_id for proper log filtering
• Agent execution spans inherit execution.id from parent "Evaluation" span
• No intermediate root span cluttering the trace hierarchy

Span Hierarchy

Before (with root span):

Evaluation Set Run
  └─ Evaluation
     └─ root  ← unnecessary intermediate span
        └─ Agent run

After (with create_root_span=False):

Evaluation Set Run
  └─ Evaluation
     └─ Agent run  ← directly under Evaluation

Testing

• Maintains backward compatibility (default: True)
• All existing tests pass
• Used by uipath-python eval runtime
