updata for chatapi

[42Wor]

We need to update the Google Gemini API package to the latest version.

Tasks:

• Update the @google/generative-ai package to latest version
• Test that chat messages still work correctly
• Check that error messages show up properly

Reason:

• Keep dependencies up to date
• Ensure compatibility with latest API features
• Fix any potential security issues

Notes:

• Make sure the API key configuration still works
• Verify chat history loading isn't broken
• Test both sending messages and receiving responses
