fix: show apps hint command in stripe --help

[yahanxing-stripe]

Summary

This PR fixes the issue that stripe apps was not appearing under "Other commands" in stripe --help.

Root cause:

When the CLI starts up, resources_gen.go auto-generates an apps resource command and sets rootCmd.Annotations["apps"] = "namespace".
RemoveAppsCmd then deletes the cobra command to cede the namespace to the apps plugin, but never cleaned up the annotation.

The help template's "Other commands" section filters out any command with an entry in rootCmd.Annotations:

  {{if (not (or (index $.Annotations $cmd.Name) $cmd.Hidden))}}

So the hint command added by AddHintCommands was registered and runnable (stripe apps worked) but invisible in --help due to the stale annotation.

This is safe — the annotation's only consumers (the help template and showInResources) both operate on the apps command, which is already removed.
