[Release] google/adk-python v2.6.1: v2.6.1

Google ADK Python v2.6.1 release introduces enhanced telemetry capabilities for CLI operations, including parent terminal grouping, TTL pruning, and TTY connectivity tracking. Bug fixes address early telemetry recording for long-running web servers and eliminate redundant tool confirmation validation. This update improves observability and performance of the ADK CLI toolchain.

Key Points

• •Added parent terminal grouping to ADK CLI telemetry for better session organization and tracking
• •Implemented TTL pruning in telemetry to automatically clean up expired or stale telemetry data
• •Enhanced CLI environment telemetry to capture TTY connectivity status for improved diagnostics
• •Fixed early telemetry recording for long-running web servers to capture complete lifecycle data
• •Implemented proper exit code logging upon routine teardown for better process monitoring
• •Eliminated redundant re-validation of already-consumed tool confirmations to improve performance
• •Improved observability of CLI operations through enhanced telemetry collection mechanisms
