Set up Adwarp for me. It's the open-source ad agent for LinkedIn Ads and Google Ads: https://github.com/adwarp-dev/adwarp

1. Check that Node.js 20 or newer is installed.
2. Walk me through creating my own LinkedIn developer app with the Advertising API product: https://github.com/adwarp-dev/adwarp/blob/main/docs/linkedin-app.md
3. Save the app's client ID and secret to ~/.adwarp/config.json as clientId and clientSecret.
4. Run "npx -y adwarp auth login" and wait while I approve access in my browser.
5. Add Adwarp to the AI client I'm using right now as an MCP server that runs "npx -y adwarp mcp". In Claude Code that's: claude mcp add adwarp -- npx -y adwarp mcp
6. Check the connection by listing my ad accounts, then save the one I pick as defaultAccountId in ~/.adwarp/config.json.

Don't create or change anything in my ad accounts during setup. LinkedIn campaigns start as drafts, so nothing spends until I turn it on.
