Add Python 3.13 Support and Fix Test Hanging Issues

[Vectorrent]

This pull request adds official support for Python 3.13 to the Hivemind project and fixes test hanging issues.

Changes

1. Fixed Python 3.13 deprecation warnings:

   • Replaced datetime.utcnow() with datetime.now(timezone.utc) in tests/test_auth.py
   • Replaced deprecated pkg_resources with modern alternatives:
     • Used Path-based approach instead of resource_filename in tests/test_utils/p2p_daemon.py
     • Replaced parse_requirements with direct file reading in setup.py
     • Replaced parse_version with packaging.version.parse in setup.py

2. Updated version support:

   • Added Python 3.13 to the list of supported versions in setup.py classifiers
   • Added Python 3.13 to the GitHub Actions test matrix in .github/workflows/run-tests.yml

3. Fixed test hanging issues in test_averaging.py:

   • Added proper try-finally blocks for resource cleanup
   • Added pytest timeout markers to critical tests
   • Improved timing logic and increased timeouts for stability
   • Fixed indentation issues that were causing test failures

Testing

• All tests pass on Python 3.13.3, including the previously hanging test_averaging.py
• No Python 3.13-specific errors were found
• Backward compatibility maintained with Python 3.9-3.12

Notes

• The bitsandbytes dependency works correctly with Python 3.13
• All changes are backward compatible and don't break existing functionality
