Error: No such command 'proxy'.

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'.
```

Start by reproducing the Windows command from the issue with the installed localstack-extension-aws-replicator package and inspect the `localstack aws` CLI entry point and its command registration. Determine why `proxy` is not available, then verify that the extension command is recognized and accepts `-c proxy_config.yml`.
