Basic Test Coverage

[aryasoni98]

Context:
The SDK has limited test coverage. We need at least smoke tests to ensure imports, basic flows, and plugins don’t break.

Tasks:

• Add pytest tests for critical modules
• Add CI action for running tests on PRs
• Ensure contributors can run pytest locally

Impact:
Improves reliability and builds trust → essential for scaling adoption.

Added more sophisticated tests now. pytest and CI actions were there before already.
