流媒体会话会在 glibc malloc arena 中留下大量不归还操作系统的冷匿名内存，实测单个 服务可累积到 2.5 GB 并占满整个 swap 文件（33 个 64/128 MB 匿名段，空闲时不增长， 随会话单调抬升）。本次从根因与兜底两侧处理： - systemd/maa-online-server.service: 设置 MALLOC_ARENA_MAX=2，把线程 arena 数量 从 8xCPU 压到 2，抑制 arena 膨胀 - systemd/maa-daily.service: 单元结束时经 ExecStopPost 重启 API 服务，回收当次会话残留 - systemd/maa-online-recycle.service, maa-online-recycle.timer: 新增每日 03:59（游戏 每日刷新前）独立回收定时器，错开更新与日常任务窗口，Persistent=false 避免补跑撞车 - bin/maa-online-can-recycle: 回收守卫，检测日常任务（systemd 单元或手工运行）是否 进行中，是则跳过回收，避免重启打断任务 - bin/maa-online-install-systemd: 安装并启用新增的回收单元 - README.md, user_config/README.md: 补充内存回收机制与定时器说明
