Subject: [PATCH] refactor: appiattisce docker/build/ in docker/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Con la rimozione di docker/dev/ non serve più distinguere due
container: Dockerfile e build.sh salgono di un livello, con i path
relativi (PROJECT_ROOT, keystore) aggiornati di conseguenza.
