* chore: update Python version requirement and remove deprecated dependencies in pyproject.toml files

* Updated Python version requirement to allow up to 3.14 in both main and base pyproject.toml files.
* Removed deprecated dependencies: cohere and pyautogen from the main dependencies list.

* chore: update Python version requirements and add support for Python 3.13 in uv.lock

* Updated the required Python version to allow up to 3.14.
* Adjusted resolution markers for Python versions to include 3.13.
* Added markers for the 'typing-extensions' dependency to restrict it for Python versions below 3.13.
* Included additional wheel files for various packages to support Python 3.13 compatibility.

* Update Python version requirements in README files to support Python 3.13

* Update Python version in GitHub Actions workflow to 3.13

* Update Python version in GitHub Actions workflows to include 3.13

* Update installation documentation to support Python 3.13 and clarify troubleshooting steps

* revert changes to docs until we release

* chore: add ag2 dependency and update uv.lock for Python 3.13 compatibility

* Added ag2 version 0.3.2 and 0.5.2 to pyproject.toml and uv.lock with appropriate resolution markers for Python versions.
