Update Min Version of Python to 3.10

[ParagEkbote]

Why This Is Important

• Compatibility: Many modern libraries and frameworks are dropping support for versions below 3.10.
• Security: Older Python versions may no longer receive security updates, increasing risk.
• Maintainability: Ensures consistency across development, CI/CD pipelines, and production environments.

Tasks

• Update pyproject.toml to require python >= 3.10.
• Modify GitHub Actions workflows to use Python 3.10 as the default runtime.
• Update documentation (README, contributing guide) to reflect the new minimum version.
• Test the codebase against Python 3.10 to confirm compatibility.
• Remove support statements for Python versions below 3.10.

Acceptance Criteria

• Project configuration files specify Python 3.10 as the minimum required version.
• GitHub Actions CI runs successfully with Python 3.10.
• Documentation clearly states Python 3.10+ is required.
• Codebase runs without errors or regressions under Python 3.10.
• No references to unsupported Python versions remain.
