refactor: rename pr +close to pr +refuse

The `pr +close` shortcut called the `refuse_merge` API, which is
misleading — "close" suggests a benign operation, but the actual
behavior is to refuse/reject the pull request permanently.

Rename the shortcut to `pr +refuse` so the name matches the API
semantics, and add a warning in the docs that it must never be used
as a substitute for `pr +merge`.

 1. 使用 `pr +view -i <id>` 确认 PR 状态为 open（`pull_request_status: 0`）
-2. 确认用户确实要关闭此 PR（此操作会拒绝合并）
-3. 执行 `pr +close -i <id>`
+2. 确认用户确实要**拒绝**此 PR（此操作不可逆，会关闭 PR 并标记为已拒绝）
+3. 执行 `pr +refuse -i <id>`
 
 ## 注意事项
 
 - 此操作调用 `refuse_merge` 端点，即**拒绝合并**
-- 关闭后 PR 状态变为 closed（`pull_request_status: 2`）
+- 拒绝后 PR 状态变为 closed（`pull_request_status: 2`）
+- ⛔ **不要用 `pr +refuse` 代替 `pr +merge`**：如果 PR 已被手动合并到 master，不要使用此命令来关闭 PR
 - 需要对仓库有相应权限
