Enable thinking config gemini realtime

[oOPa]

Description

Adds support for passing a thinkingConfig option through the Google LiveKit plugin Realtime API so callers can control Gemini’s thinking behavior during response generation. Also updates the Google GenAI SDK dependency to a newer version. This version bump is needed to expose the thinkingConfig field.

I'm introducing this change to be able to disable thinking on realtime modesl because dynamic thinking is enabled by default.

Changes Made

• Add thinkingConfig to realtime options and session payload in realtime_api.ts.
• Plumb thinkingConfig from RealtimeModel options into session creation.
• Bump @google/genai to ^1.34.0 (lockfile updated).
