Bug: Adding urllib3>=2.6.0 breaks installation on Python 3.8, which contradicts the project's documented support for Python 3.8+.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

The project's documentation claims support for Python 3.8 and higher. This pull request introduces a dependency on urllib3>=2.6.0, which requires Python 3.9 or later. This will cause a pip dependency resolution failure for any user attempting to install the project on a Python 3.8 environment, directly contradicting the documented system requirements. The CI pipeline does not test against Python 3.8, so this breaking change was not detected automatically.

💡 Suggested Fix

To resolve this, either update the documentation to reflect that Python 3.9+ is the new minimum required version, or downgrade the urllib3 requirement to a version compatible with Python 3.8 to maintain the currently documented support.
