 Three packages hand-roll promise-wrapped timers that the `node:timers/promises` builtin already provides, while other packages (`dsh-llm-mock-server` `pause()`, `dsh-lsp-stdio`, `dsh-acp-snapshot`) already use the builtin — so the hand-rolled copies are also a consistency gap:
 
 - `packages/llm/llm-retry/src/index.ts` `cancellableDelay()` (~14 lines): `new Promise` + `setTimeout` + manual abort-listener add/remove, resolving `true` on elapse and `false` on abort, consumed once for the backoff wait.
-- `packages/workflow/workflow-worker-thread/src/host.ts` `sleep()` (~7 lines): promise-wrapped unref'd `setTimeout` used as the dispose-grace bound.

 - `packages/terminal/terminal-bash/src/session.ts` `delay()` (~4 lines): bare promise-wrapped `setTimeout` used in polling/teardown waits.

 三个包手写了用 promise 包装的定时器，而 `node:timers/promises` 内置模块早已提供同等能力；其他包（`dsh-llm-mock-server` 的 `pause()`、`dsh-lsp-stdio`、`dsh-acp-snapshot`）已经在使用该内置模块，因此这些手写副本同时也是一处一致性缺口：
 
 - `packages/llm/llm-retry/src/index.ts` 的 `cancellableDelay()`（约 14 行）：`new Promise` + `setTimeout` + 手动添加和移除中止监听器，定时器触发时 resolve 为 `true`、被中止时 resolve 为 `false`，仅在退避等待处消费一次。
