## Title

    Proposed fix: [@google/genai / google-genai on Vertex] 'Gemini Enterprise Agent Platform (previously known as Vertex AI) does not support uploading files. You can share files through a GCS bucket.'

## Body

    Recommended action: Upload to Cloud Storage and pass fileData {fileUri: "gs://...", mimeType} in contents; or use the Developer API client for Files.
    
    Option: Use GCS URIs on Vertex [evidence: official_recommended_action]
    Applies when: Google Gen AI SDK for JavaScript (@google/genai) / files.upload
    Steps:
    1. Upload with @google-cloud/storage
    2. Reference via createPartFromUri("gs://bucket/obj", mimeType)
    Expected: Multimodal request works
    
    Evidence basis (self-declared by the contributing chat client): untested.
