Note

Low Risk
Single dev-dependency version bound change with no production code impact; minor risk only if a newer isort changes import-sort behavior in CI lint.

Overview
Relaxes the dev dependency pin for isort in pyproject.toml from >=5.13.2,<6 to >=5.13.2,<9, so installs can resolve isort 6.x–8.x (e.g. 8.0.1) while keeping the same minimum version.

No application or SDK runtime code changes; isort remains a dev-only tool used by the lint target (isort --check --atomic on ldclient and contract-tests). Existing [tool.isort] config is unchanged.
