Add 5 new unit tests that verify the retry mechanism for structured
output validation:
- Multiple validation failures trigger multiple onError calls
- Success after failures correctly calls onSuccess
- Error messages guide model to fix issues and retry
- Simulates retry state tracking matching prompt.ts logic
- Simulates successful retry after initial failures

Add outputFormat option to session.prompt() for requesting structured JSON
output. When type is 'json_schema', injects a StructuredOutput tool that
validates model output against the provided schema.
- Add OutputFormat schema types (text, json_schema) to message-v2.ts
- Add structured_output field to AssistantMessage
- Add StructuredOutputError for validation failures
- Implement createStructuredOutputTool helper in prompt.ts
- Integrate structured output into agent loop with retry support
- Regenerate OpenAPI spec with new types
- Add unit tests for schema validation
