#9910 test: Handle Python 3.15 warning coming from transitive dependency pygments Pull request opened by edgarrmondragon Description SSIA.

Build: • Add a pytest warning filter in pyproject.toml to ignore the pygments DeprecationWarning about os.path.commonprefix on Python 3.15. CI: • Remove the global PYO3_USE_ABI3_FORWARD_COMPATIBILITY environment variable from the GitHub Actions test workflow and rely on environment configuration within nox sessions instead. Tests: • Set PYO3_USE_ABI3_FORWARD_COMPATIBILITY within the nox _uv_sync session environment so that test environments retain the required Pyo3 ABI compatibility setting. meltano/meltano
