smix-cli 0.1.0

//! v5.1 c7 — `smix selftest multi` CLI subcommand 实现。
//!
//! 调 smix-sdk 的 `selftest::multi::run_multi_selftest`。CLI 层只做:
//! 1. argv 解析(`<UDID>:<PORT>` × N)
//! 2. runs_root 计算(`.smix/selftest-multi/<RFC3339>/`)
//! 3. exit code 映射(0=all_pass / 1=some_fail / 2=IO Err / 64=usage)
//!
//! 前置假设(gate-multi.sh 打包):每个 UDID 已用 `smix capsule up <UDID>
//! --runner-port <PORT>` 起好。CLI 不自起 capsule(scope 控);要 gate
//! 三连就走 `scripts/v5/selftest-gate-multi.sh`。
