+    ## Configuration
+    ### API graceful shutdown window
+    - Env: `EXECD_API_GRACE_SHUTDOWN` (e.g. `500ms`, `2s`, `1m`)
+    - Flag: `--graceful-shutdown-timeout`
+    - Default: `1s`
+    This controls how long execd keeps SSE responses (code/command runs) alive after sending the final chunk, so clients can drain tail output before the connection closes. Set to `0s` to disable the grace period.

+    ## 配置
+    ### SSE API 优雅结束时间窗口
+    - 环境变量：`EXECD_API_GRACE_SHUTDOWN`（如 `500ms`、`2s`、`1m`）
+    - 命令行参数：`--graceful-shutdown-timeout`
+    - 默认值：`1s`
+    作用：控制 SSE 响应（代码/命令执行）在发送最后一块数据后，保持连接的宽限时间，方便客户端完全读到尾部输出再关闭。如果设置为 `0s` 则关闭这一等待。
