This PR fixes several regressions that made the library unusable:

  1. Python Fix: In whatsfly/whatsapp.py, I fixed a typo **message ** message["content"] which was both invalid Python syntax and logically incorrect for non-dictionary content (like the QR code). It now safely merges only dictionary content.
  2. Go Fix: In backend/clientAbstract.go, I fixed a type assertion from string to []byte and resolved a memory leak by moving C.free out of a defer inside the message thread loop.
  3. Testing: Added tests/test_handle_message.py to ensure robust event handling.

The backend was successfully built with go build -buildmode=c-shared, and the Python fixes were verified with the new unit test.

- Fixed a syntax error and unsafe dictionary merging in `whatsfly/whatsapp.py` that prevented the QR code from displaying.
- Fixed a type assertion crash and a critical memory leak in `backend/clientAbstract.go`'s message loop.
- Added a new unit test `tests/test_handle_message.py` to verify event processing logic.
