Marketplace.json lists 2248 plugins (max 2000) Error

Adding the marketplace in Claude Desktop with third-party inference enabled causes the following error:
```
1 configured marketplace couldn't load
anthropics/claude-plugins-community: marketplace.json lists 2248 plugins (max 2000)
```

Start by inspecting marketplace.json and counting its plugin entries against Claude Desktop's documented 2,000-plugin limit. Determine what change is needed so the published marketplace loads without the reported error, then verify the resulting marketplace count and loading behavior.
