What's Wrong?

When you uninstall a plugin through the UI, it removes it from the enabledPlugins list in settings.json but doesn't clear
the corresponding entry from installed_plugins.json. So the plugin still appears as "Installed" even though you've uninstalled it.

What Should Happen?

• Steps: install plugin → uninstall → go to Marketplaces → plugin still shows as "Installed plugins (1)"
• Expected: plugin removed from installed list, Install button shown
• Actual: stale installed_plugins.json entry persists
