[BUG] Co-Work fails to uninstall locally-uploaded plugins

What's Wrong?

When attempting to uninstall a plugin that was uploaded locally through the
Claude Desktop UI, the desktop app delegates to the CLI command claude plugin
uninstall <name>@local-desktop-app-uploads --cowork inside the VM. The CLI
does not recognize locally-uploaded plugins as "installed plugins" — it only
tracks plugins installed via the CLI's own marketplace flow. The command exits
with code 1 and the plugin remains installed.

What Should Happen?

Locally-uploaded plugins should be uninstallable from the same UI that was
used to install/enable them. Either:

• The CLI's plugin uninstall command should be aware of locally-uploaded

plugins in the marketplaces/local-desktop-app-uploads/ directory, or

• The desktop app should handle uninstallation of local plugins directly

(removing the files from the
cowork_plugins/marketplaces/local-desktop-app-uploads/ directory and
updating settings) without routing through the VM CLI

 **Note:** This error has reproduced on two separate attempts (Feb 23 at
 14:27:56 and Feb 23 at 20:12:32), both with the same result.

Steps to Reproduce

1. Upload a local plugin to Co-Work via the Claude Desktop UI (the plugin ends

up in cowork_plugins/marketplaces/local-desktop-app-uploads/)

1. Enable the plugin
2. Attempt to uninstall the plugin from the Co-Work plugin management UI
3. The UI will display "Failed to uninstall plugin"
4. The plugin remains installed and enabled
