[Bug]: Missing dependencies for A2AClient (googleapis-common-protos, grpcio, protobuf) #892
Description
What happened?
Starting from version 0.2.14, it seems that the dependencies required for using A2AClient - namely googleapis-common-protos, grpcio, and protobuf — are no longer installed automatically.
As a result, importing A2AClient now causes ModuleNotFoundError unless these packages are installed manually.
These dependencies may need to be added back to the installation requirements.
