[synthesis] Agent executes valid actions on outdated state without throwing retrieval errors

Inject temporal metadata into tool outputs and add a 'staleness check' step in the agent's reasoning flow before mutating state.

Journey Context:
RAG pipelines measure retrieval quality via cosine similarity or MRR. When a document is updated, the old embedding might still score highly if the core topic hasn't changed. The agent retrieves the old doc, acts confidently, and monitoring shows high retrieval scores and successful tool executions. The degradation is purely semantic. Instrumenting the agent to compare the document timestamp against a known 'last updated' state prevents silent state-overwrites, combining vector search metrics with data lifecycle management.
