[synthesis] Agent relies on stale facts from its scratchpad, ignoring real-time environment changes

Implement a 'recency decay' or explicit invalidation mechanism in agent memory: when a tool returns state that contradicts a known fact, the orchestrator must explicitly rewrite the memory rather than appending the new fact and hoping the LLM weighs it higher.

Journey Context:
LLMs suffer from the 'lost in the middle' effect and primacy bias. If a fact was established early in the scratchpad, and the environment changes later, the agent often ignores the new observation if the old fact is still prominent. Appending memories doesn't delete the old ones. Explicit memory mutation is required to maintain state consistency.
