Pull Request Overview

This PR adds functionality to extend Gemini Live sessions indefinitely by implementing session resumption and automatic reconnection when "go away" signals are received. The changes enable the system to maintain conversation context across session boundaries while handling service interruptions gracefully.

• Adds context window compression and session resumption configurations to the Gemini Live client
• Refactors session management to use a Ref-based approach enabling dynamic session replacement
• Implements automatic session resumption logic when receiving "go away" signals from the Gemini API

Using getOrElse(\"\") for the handle parameter could be problematic. Consider using handle.orNull or checking if the SessionResumptionConfig should only be set when a handle is provided, as an empty string might not be a valid handle value.
