//   - engaged: LastActionDate stamped today/yesterday → streak bumps
//   - activity-without-tap: autopilot/background activity logged today but
//     no LastActionDate stamp → streak holds, no shame DM, no decay
//   - truly idle: nothing anywhere → streak halves, StreakDecayed=true
//
// Regression guard for the autopilot bug: a player who let the background
// auto-run walk an expedition all day used to get shamed at midnight because
// markActedToday is gated on !compact at dnd_zone_cmd.go.
