feat(ai): Enhance Google provider telemetry and AI object response handling

This commit introduces two key improvements:

1.  **Google Provider Telemetry:**
    - Updated  to include token usage data (, ) in the responses from  and .
    - This aligns the Google provider with others for consistent AI usage telemetry.

2.  **Robust AI Object Response Handling:**
    - Modified  to more flexibly handle responses from .
    - The add-task module now check for the AI-generated object in both  and , improving compatibility with different AI provider response structures (e.g., Gemini).

These changes enhance the reliability of AI interactions, particularly with the Google provider, and ensure accurate telemetry collection.
