fix: update pytest and dependencies for Python 3.13 compatibility

- Updated pytest to >=8.3.0 (required for Python 3.13 support)
- Updated pytest-cov to >=5.0
- Updated pytest-xdist to >=3.5
- Updated pytest-timeout to >=2.3
- Added pytest-anyio>=4.0 for async test support with Python 3.13
- These version requirements ensure compatibility with Python 3.13
- No need to disable Python 3.13 in CI matrix
