In Options > Plugins, right-clicking a plugin whose source is a local directory (e.g. local git repo) and selecting "View Repository" (or "View Directory") does nothing.

Steps to Reproduce

1. Have a plugin installed whose source/remote is a local filesystem path (e.g. D:\git\my-plugin).
2. Open Options > Plugins, right-click the plugin, and click "View Repository" (or "View Directory").

Expected Result

The directory opens in the system file manager.

Actual Result

Fails silently. Nothing opens and no error is logged.

Cause

In PluginListWidget._view_repository(), remote_url is passed directly to QtCore.QUrl(remote_url). On Windows, passing a path like D:\... causes Qt to treat the drive letter D: as the URL scheme (d:), which QDesktopServices.openUrl() fails to handle.
