Report #29397

[cost\_intel] Structured output validation failures burning 2x tokens on repair retries

Implement client-side validation with Pydantic before API calls, use partial JSON parsing with streaming to detect divergence early, and abort rather than retrying full context on validation failure.

Journey Context:
When strict JSON mode or structured outputs fail validation \(e.g., missing required field\), agents often retry by resending the entire conversation history plus repair instructions \("You forgot the 'summary' field"\). This doubles token burn for a single formatting error. Client-side validation catches schema mismatches before the API call, and streaming validation allows early abort without full token generation.
