Important

Add environment variable to control IO capture in @observe decorator, improving performance for large objects.

• Environment Variables:
  • Add LANGFUSE_OBSERVE_DECORATOR_IO_CAPTURE_ENABLED to environment_variables.py to control IO capture in @observe decorator.
  • Default value is True, allowing automatic capture of function args, kwargs, and return values.
• Decorator Behavior:
  • Modify LangfuseDecorator.observe() in observe.py to check LANGFUSE_OBSERVE_DECORATOR_IO_CAPTURE_ENABLED.
  • IO capture (capture_input and capture_output) is conditional on the environment variable being True.
• Performance:
  • Disabling IO capture can improve performance for functions with large or deeply nested objects.
