Adds strict mode to four maintenance scripts, with guards so expected non-zero exits (empty beet queries, a missing config, a curl timeout) log/skip instead of aborting: gen-djmix bails cleanly if djmix-albums.txt is absent and tolerates a bad single query; gen-vgm tolerates an empty query; strip-mb-tags quotes its path arg and best-efforts the trailing beet update; notify-telegram guards curl so a network error still reaches its explicit "send failed" branch.
