[Bug] Plugin appears installed in discover but not functional; symlinked .claude directory causes state mismatch

Bug Description
I'm not able to install the commit-commands plugin from your marketplace. It doesn't show in installed plugins, but when I find it in discover, it appears as installed! (/commit etc. doesn't work)

My .claude is a symlink and settings.json has

{
  "enableAllProjectMcpServers": true,
  "enabledPlugins": {
    "code-simplifier@claude-plugins-official": true,
    "commit-commands@claude-plugins-official": true
  }
}

_Removing commit-commands from the settings doesn't change anything - it still says Installed in marketplace..._

Yesterday I installed commit-commands in another repo as shared in this repo and that was the sam I wanted in this failing repo. My user installed plugins works in both repos.
