Enum CommitMode 

pub enum CommitMode {
    MemoryOnly,
    AsyncDurable {
        group_window_ms: u32,
    },
    SyncDurable,
}

写入持久性与延迟之间的权衡。

• MemoryOnly：事件入内存队列即返回，最低延迟、不具持久性，仅适合演示/开发。
• AsyncDurable：写入 WAL/系统缓存后返回，fsync 由后台分组处理； 在桌面环境具有很好的实际持久性与极低延迟（默认）。
• SyncDurable：提交前强制 fsync，延迟最高、持久性最强。
