[architecture] Retrieved memories polluting current context with outdated information

Implement a composite scoring function for memory retrieval that weights recency and importance alongside cosine similarity, and validate retrieved memories against current context before injection.

Journey Context:
Pure cosine similarity retrieval ignores time. An old bug fix might perfectly match a current bug symptom, but the codebase has since changed, making the old fix harmful. Developers often try to solve this by just increasing 'k', which adds more noise. The right call is a composite score: alpha \* similarity \+ beta \* recency \+ gamma \* importance. Recency decay ensures stale state fades unless explicitly marked as persistent.
