## Summary of the Pull Request
This PR adds a cache of command provider information so we can show
providers even when the command provider isn’t loaded.
It also updates the description for disabled extensions on the
Extensions page to always include the extension name.
Finally, it adds a placeholder icon for cases where an extension icon
isn’t loaded. Note that this doesn’t address fully transparent icons
that some extensions may inherit from the default template.
