Overview

Unified per-entry lifecycle policy (ADR 0079): one ttl + one action. Replaces the separate Fetch (ttl/on_stale) and Retention (expire_after/archive_after) policies. The action’s destructiveness decides WHERE it runs: lazy actions (refresh/warn) on get/list reads; destructive actions (drop/archive) only on the tend sweep.
