adk-python v1.35.1 improves streaming and metadata handling

This patch release for google/adk-python addresses two specific issues. It ensures grounding metadata is sent correctly for live 3.1 interactions and guarantees the final partial=False frame is always yielded in streaming scenarios. These fixes are relevant for developers using the adk-python library, particularly those working with streaming APIs or live interactions.

• →Only send grounding_metadata for 3.1 live at the end of each turn
• →Ensure final partial=False frame is always yielded
