Report #100248

[architecture] Old memories drown out recent ones and the store grows forever.

Add eviction and decay: summarize and archive oldest conversation turns, expire transient tool outputs with TTLs, and retrieve by recency \+ relevance \+ importance rather than pure similarity.

Journey Context:
MemGPT treats the context window as constrained RAM and uses OS-style paging: a FIFO queue, working context, and external archival store. Without active curation, vector stores accumulate stale entries that rank highly by accident. Summarization compresses history, TTLs delete ephemeral observations, and scoring functions keep retrieval focused on what matters now.
