## Title

    Proposed fix: [Foundry agent optimization] 'evaluators is required and cannot be empty' / 'No optimizable element found for the hosted agent' / AllEvaluatorsFailedError / 'optimization_model is requir

## Body

    Recommended action: Add header Foundry-Features: AgentsOptimization=V2Preview; include system_prompt/tools/skills in optimization_config; start with builtin.task_adherence; pass --optimize-model gpt-5 or set optimization_model in eval.yaml; use exact deployment names.
    
    Option: Send preview header and targets [evidence: official_recommended_action]
    Steps:
    1. Foundry-Features: AgentsOptimization=V2Preview
    2. optimization_config with system_prompt
    3. --optimize-model gpt-5
    Expected: Job starts
