Not entirely sure what triggers that warning, I simply ensured I had correctly filled in the readme.txt ?

which you appear to have as well, wonder if it has to do with the loader.php or at least having a file with that name or similar I used upm-loader.php to initialize and call the main file slightly unnecessarily as I remember thinking as could quite easily have worked from the main file and run the BP init check
