Metona Build
69a28a8500
Fix 2 - 类型安全: - (window as any).metonaDesktop → window.metonaDesktop - any[] → Record<string, unknown>[] - 回调 :any → ChatSession | null - 78 处 → 38 处（减少 51%） Fix 3 - 架构拆分: - tool-handlers.ts (1308行) → 4 个模块: - tool-handlers-shared.ts: 共享工具函数 - tool-handlers-fs.ts: 15 个文件系统操作 - tool-handlers-system.ts: 6 个系统网络操作 - tool-handlers-git.ts: 1 个 Git 操作 Fix 4 - 记忆数据治理: - 90 天未使用自动降低 importance - 清理评分新增 agePenalty - 向量错误日志增强（记忆ID、内容摘要、模型、栈） - 去重增强（前缀匹配）
