[architecture] Single agent verifies its own work leading to blind spots and sycophancy

Implement an independent 'Critic' or 'Verifier' agent with a distinct system prompt and isolated context. The Verifier agent should only receive the input requirements and the output artifact, explicitly instructed to find flaws, without access to the Generator's reasoning process.

Journey Context:
Self-reflection \(Generator \+ Critic in the same prompt/agent\) often results in sycophancy—the LLM agrees with itself. True verification requires isolation. The Verifier must not see 'I did X because Y', otherwise it will be biased by the Generator's rationale. This mirrors code review: reviewers see the PR diff, not the author's internal thought process. The tradeoff is doubling the compute cost for the verification step, but it dramatically reduces error rates for complex tasks.
