refactor: Improve progress notification handling in handle_call_tool - Updated the logic for progress task creation in the `handle_call_tool` function to ensure it only initializes when progress notifications are enabled and a progress token is present. - Enhanced the cancellation and exception handling of the progress task to prevent potential errors when it is not created. - Improved overall robustness of the function by ensuring that progress updates are managed correctly based on the current context.
