# Runs all media maintenance scripts sequentially in the order defined in Master.conf.
# Each job in MEDIA_MAINTENANCE_JOBS is a script path with an optional argument.
# Scripts are resolved relative to the ecosystem root directory.
#
# To add a new job — edit MEDIA_MAINTENANCE_JOBS in Master.conf:
#   "Media/my_new_script.sh"           — script with no argument
#   "Media/media_cleaner.sh profile"   — script with argument
#
# Order matters — permissions runs before cleaners so files are correctly owned first.
# Each job runs independently — a failure in one does not stop the others.
# Supports --dry-run — passes through to all child scripts.
