[architecture] Old context or outdated memories polluting new agent answers

Implement memory decay and explicit overwrite mechanisms. Score retrieved memories by a composite of recency, importance, and relevance. Provide the agent with an explicit 'update\_memory' or 'overwrite\_fact' tool to invalidate stale data rather than just appending new data.

Journey Context:
Agents often just append to memory, leading to a noisy retrieval space where outdated facts \(like an old address\) compete with new ones. Without time-based decay, old but highly semantically similar facts will pollute the context. Without explicit overwrite tools, the agent cannot correct itself, leading to hallucinations where it merges the old and new facts.
