Pre push build for nextjs which utilises git worktree to avoid replacing the .next folder with a production build, then requiring a restart of npm run dev.

Improvements could be build/main default branch needed - could use an env but this is to avoid switching back to a branch in-use by the parent worktree repository

The /tmp/ directory should most likely have an environment variable, or use ../SAME_FOLDER_NAME__TMP
