[architecture] Agent memory grows infinitely and degrades retrieval precision

Apply a time-decay factor to memory embeddings or scores. When a memory's relevance score drops below a threshold, archive it or summarize it into a higher-level node.

Journey Context:
Storing every interaction forever makes the vector space noisy. Exact matches become rare, and semantic search returns conflicting historical states. Summarization and decay keep the active memory lean and focused on the present state, preventing retrieval dilution where highly specific but obsolete facts outrank general current truths.
