feat: add comprehensive client library and CI workflow (#13)

* reduce CI matrix to mainstream Python versions

- Remove Python 3.9 support to focus on mainstream versions
- Keep Python 3.10, 3.11, and 3.12 for better coverage/performance balance

* clean up AI dependencies from client library PR

- Remove unnecessary AI-related optional dependencies
- Keep only lint and test dependencies for client library
