Desktop CI/CD and end-to-end testing feels unreasonably chaotic compared to web/server workflows.

For web, I run `vercel` or `next build` locally and I'm done. For desktop apps (Swift, Electron, Tauri, GPUI), I'm juggling different platforms, manually configuring runners for each OS/architecture combination, and constantly context-switching between my IDE and various web dashboards.

Why isn't there a CLI where I can just run something like `build --matrix=macos-arm,windows-x64,linux` from my terminal? Or a platform that auto-detects the project type the way Vercel detects Next.js? Custom Docker images and proper caching seem table-stakes for web CI but rare for desktop.

Am I missing something obvious? What are people using for this?
