ekg-memory integration: record repeated-error incidents to memory and use memory-linked signatures for earlier escalation

 > 为什么需要时间窗口：
 > 历史全量统计会被旧数据与 heartbeat 噪音稀释，导致当前阶段决策失真。建议默认观察近 24h（或 6h/7d 可切换），让 fallback 和告警更贴近“当前”系统状态。

+- EKG-memory integration: repeated-error escalation writes structured incidents to `memory/YYYY-MM-DD.md` and `MEMORY.md`, and future advice can escalate earlier for known signatures
 
 > Why time windows matter:
 > Full-history stats get diluted by stale data and heartbeat noise, which degrades current decisions. A recent window (e.g., 24h, optionally 6h/7d) keeps fallback and alerts aligned with present runtime behavior.
