Krzysztof kuhy Rudnicki	de7d5d17eb	sql_drills: no root shell for learner SQL ... Learner SQL piped into the mysql client could run `\! id` as container root and read every DB. Now: --binary-mode (client commands error out), a refused-backslash-line guard, learner exec as uid 65534, and a random root password (0600 file, via env, adopted live on a legacy container).
