[research] Agent outputs degrade silently over iterations without throwing exceptions

Implement inline LLM-as-a-judge evaluators at the end of every agent step or tool output, specifically checking for hallucination or task drift alongside standard schema validation.

Journey Context:
Traditional software fails loudly \(exceptions, stack traces\). LLM agents fail silently by returning confident but incorrect text that parses successfully. Relying solely on output schema validation misses semantic errors. Adding a lightweight, fast LLM evaluator as a post-processor to score the output against the original prompt catches these drifts before they compound in multi-step agentic loops.
