-The tool owns its `presentCall`/`presentResult` render intent. A call is a `terminal` card carrying command, description, and optional cwd; a completed result is a `generic` card with the rendered output in a `console` fence. The bash tool's terminal card with its parsed exit-status pill has no pwsh counterpart yet — a PowerShell-aware presentation is roadmap work. These presenters are pure and replay-safe.
+The tool owns its `presentCall`/`presentResult` render intent. A foreground call is a `terminal` card carrying command, description, and optional cwd; a `run_in_background` call is a `generic` card with the raw command, mirroring the bash tool's background presentation. A completed result is a `generic` card with the rendered output in a `console` fence. The bash tool's terminal card with its parsed exit-status pill has no pwsh counterpart yet — a PowerShell-aware presentation is roadmap work. These presenters are pure and replay-safe.

-工具拥有自己的 `presentCall`/`presentResult` 呈现意图。调用是携带命令、描述与可选 cwd 的 `terminal` 卡；完成的结果是以 `console` 围栏包裹渲染输出的 `generic` 卡。bash 工具那种带解析退出状态 pill 的 terminal 卡在 pwsh 侧暂无对应——PowerShell 感知的呈现属于路线图工作。这些 presenter 是纯函数且可重放。
