[Repo Assist] eng(tooling): correct isort py_version from 38 to 39

This PR was created by Repo Assist, an automated AI assistant.

Problem

The [tool.isort] section in pyproject.toml has py_version = 38, meaning isort treats the codebase as targeting Python 3.8. However, the project's minimum Python version is 3.9 (see python = ">=3.9,<3.14" in [tool.poetry.dependencies]).

Fix

Change py_version = 38 → py_version = 39 to align the isort configuration with the actual minimum Python version.

Impact

• Corrects isort's internal Python version assumption for import classification and standard-library detection.
• In practice, the change in import ordering between py38 and py39 is minimal (no imports in this codebase differ), so no reformatting is expected.

Test Status

This is a one-line pyproject.toml configuration change. No code logic was modified. The CI format_check step (which runs isort) will validate that no import reformatting is required.
