unit 2 - cursor IDE integration

hi, as a heads up i wasn't able to make the example run using `mcp-remote` with cursor, however the fact that Cursor only support local servers via stdio transport is no longer true, I was able to connect to my hf space hosted MCP server by changing the configuration to:

```
{
"mcpServers": {
"sentiment-analysis": {
"url": "https://jckr-mcp-sentiment.hf.space/gradio_api/mcp/sse",
"headers": {
"Accept": "text/event-stream"
},
"autoExecute": true,
"trusted": true
}
}
}
```

Open the Unit 2 Cursor IDE integration example and compare its mcp-remote instructions with the configuration shown in this issue. Update the documented Cursor setup to reflect the reported SSE connection approach, then verify the example against the referenced Hugging Face Space.
