### Version

0.6.4

### Operating System

macOS

### What happened?

error: Executable already exists: xhs (use `--force` to overwrite)

先安装了 xhs-cli，再安装 xiaohongshu-cli 提示这个。

### Expected behavior

可以同时安装

### Steps to reproduce

```bash

```

### Error output / logs

```text

```

Reproduce the macOS installation sequence by installing xhs-cli and then xiaohongshu-cli, observing the shared xhs executable conflict. Inspect the repository's packaging and CLI entry-point configuration to identify the naming collision; done means both packages install without an executable-overwrite error.
