amadeus-performance-validation

在不推进主工作流的情况下单独运行 performance-validation 阶段以执行性能检查。

单独跑 performance-validation 阶段来做性能检查，不会推进主工作流的当前阶段。常在想做一次独立的性能回归或压力验证时用，避免影响正在进行的流程。特别之处是只执行该阶段并提交一个合成 id 对，运行结束后不会改动主流程状态。

# AI-DLC Stage Runner — performance-validation

Run the `performance-validation` stage on its own. This is opt-in packaging over
`/amadeus --stage performance-validation --single`; the same stage is always reachable via
that flag without this skill.

## Steps

1. Ask the engine for the single-stage directive:

   ```bash
   bun .codex/tools/amadeus-orchestrate.ts next --stage performance-validation --single
   ```

   The engine emits one `run-stage` directive for `performance-validation` (carrying the
   lead agent, the resolved consumes/produces paths, the rules and sensors in
   context, and — on this first directive — the conductor persona). Run the stage
   exactly as the directive desc
