## Title

    Proposed fix: [google-genai] 'No API key was provided…' or 'Project or API key must be set when using the Vertex AI API.' — backend selection depends on GOOGLE_GENAI_USE_VERTEXAI and GOOGLE_CLOUD_PROJ

## Body

    Recommended action: Set GOOGLE_GENAI_USE_VERTEXAI=true plus GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_LOCATION (or pass them) for Vertex; set GEMINI_API_KEY for the Gemini Developer API. Propagate these env vars into CI/containers.
    
    Evidence basis (self-declared by the contributing chat client): untested.
