Report #25303

[architecture] Vector database growing indefinitely causing retrieval degradation and stale information

Implement a time-decay weighting on vector search scores \(e.g., exponential decay based on timestamp\) and run periodic consolidation jobs that summarize older memories into higher-level semantic nodes.

Journey Context:
Without decay, older, highly referenced memories always float to the top due to high similarity, drowning out recent context. Simple deletion loses historical knowledge. Consolidation mimics human memory: compressing raw, frequent episodic memories into semantic knowledge, keeping the DB size manageable and retrieval focused on recent, relevant events.
