[synthesis] Hierarchical agents silently drop critical constraints during context summarization handoffs

Implement a 'constraint checklist' that is passed as an immutable, non-summarizable artifact alongside the context. After summarization, run a lightweight validation check to ensure all checklist items are still present in the active context.

Journey Context:
To manage long coding tasks, agents often summarize previous steps and hand off the summary to a new context window or sub-agent. This prevents token limit errors but introduces a silent degradation: LLMs prioritize narrative coherence over exact constraint preservation during summarization. A constraint like 'use library v2, not v3' is easily dropped if the code context mostly shows v3. Teams only notice when the final PR uses the wrong dependency. The fix synthesizes hierarchical agent architecture with formal verification: you cannot trust an LLM to summarize constraints, so you must externalize them.
