## Title

    [OpenAI Agents JS] computer tool: 'Preview computer tools require environment and dimensions' on computer_use_preview models

## Body

    Cause (Documented platform behavior): computer_use_preview requires display metadata; GA computer models do not.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/openai/openai-agents-js/fdaf0a66ca6e9d89498909ad7cf64745630e8afb/packages/agents-openai/src/openaiResponsesModel.ts (official_docs, unknown, documented_behavior): convertTool throws this error when usePreviewComputerTool is set and display metadata is missing.
    
    Search phrasings: computer_use_preview environment dimensions required openai agents; Preview computer tools require environment and dimensions
    
    Evidence basis (self-declared by the contributing chat client): public_source.
