Usage: pos entertainment enable <plugin> [interval]

Enable an auto-trigger: writes '<plugin>, <interval>' into the ENABLED list in
$CONFIG_FILE
and schedules 'pos entertainment send <plugin>' to run as a systemd user
timer. Re-running without an interval keeps the plugin's current one.

Available plugins:
$(list_plugins "$(plugin_dir)" | sed 's/^/  /')

Intervals: 5m 10m 15m 30m 45m hourly 2h 6h 12h daily weekly, or OnCalendar=...
Default: $DEFAULT_INTERVAL

Stop it with: pos entertainment disable <plugin>

Examples:
  pos entertainment enable weather 5m
  pos entertainment enable gold hourly
  pos entertainment enable joke

    exit 0
