Error: No such command 'proxy'.

还没有人认领这个 Issue。

Running on windows if it matters.

I have installed the replicator extension CLI package:
```
pip install localstack-extension-aws-replicator
Requirement already satisfied: localstack-extension-aws-replicator in c:\users\redacted\appdata\local\programs\python\python313\lib\site-packages (0.1.24)
```

I try to run the extension:
```
localstack aws proxy -c proxy_config.yml
Usage: localstack.exe aws [OPTIONS] COMMAND [ARGS]...
Try 'localstack.exe aws -h' for help.

Error: No such command 'proxy'.
```

首先，使用本地安装的 localstack-extension-aws-replicator 软件包重现 issue 中的 Windows 命令，并检查 `localstack aws` CLI 入口点及其命令注册。确定 `proxy` 不可用的原因，然后验证扩展命令能够被识别并接受 `-c proxy_config.yml`。
