[Release] google/adk-python v1.35.1: Release 1.35.1

Google ADK Python v1.35.1 is a bug fix release addressing two critical issues: grounding metadata handling for 3.1 live interactions and streaming frame completion. The release ensures proper metadata transmission at turn boundaries and guarantees final partial frames are correctly yielded in streaming scenarios.

Key Points

• •Fixed grounding_metadata to only send for 3.1 live at the end of each turn, preventing unnecessary metadata transmission
• •Resolved streaming issue where final partial=False frame was not always being yielded to clients
• •Ensures proper turn-based metadata handling in live interactions
• •Guarantees streaming completion frames are delivered reliably
• •Two targeted bug fixes improving stability and correctness of core streaming and metadata features
