[architecture] Agent remembers outdated facts after the world or codebase changes

Version your memory and attach timestamps/sources; prefer recent entries when they conflict with older ones.

Journey Context:
Static vector stores have no concept of time. If a library API changes, old documentation embeddings can outrank new ones or get mixed into retrieval. Every memory entry should carry a timestamp and ideally a source/version. Retrieval should weight recency, and the agent should be able to resolve conflicts by preferring newer information. This is crucial for coding agents working with evolving codebases. The tradeoff is that you need to update or invalidate old entries rather than just appending new ones.
