Struct Envelope 

pub struct Envelope<T> {
    pub version: String,
    pub ok: bool,
    pub command: String,
    pub data: Option<T>,
    pub snapshot_id: Option<String>,
    pub duration_ms: u64,
}

统一成功 envelope。stdout 只允许出现本结构(或其错误变体)的序列化结果(ADR-002; 唯一例外 --help/--version 走人类文本,docs/06 §3.5)。

Fields

version: String

ok: bool

command: String

data: Option<T>

snapshot_id: Option<String>

duration_ms: u64
