Creates a Next.js dev helper that maps clicked UI elements to their source files via hotkey, with clean path resolution and editor integration.
I want a development helper in Next.js where in browser devtools I can press a hotkey, click a UI element, and my editor opens exactly at that component’s source line. Setup should include the inspector component + backend path so element → file mapping works in development only, with file/line properly detected and not ugly escaped paths. Do this with the shortest, safest config so it works across typical React/Next projects.
