Wifi Hoppers

Update to support Orphans due to WorldEdit

What was added

• /hopper trim (admin only)
• Scans only hoppers whose chunks are currently loaded
• For each loaded entry: reads the block at the saved coordinates
• Removes from DB only if the block is not Material.HOPPER
• Never touches hoppers in unloaded chunks, wrong-world rows, or link-only cleanup
• Reports: removed, kept, skipped-unloaded (and skipped-region on Folia if a chunk couldn’t be read from that thread)

Lazy prune (background, config-driven)

In config.yml:

maintenance:
  lazy-prune:
    enabled: true
    seconds: 30

• Only runs for hoppers already being ticked (near players, chunk loaded)
• If the block isn’t a hopper, accumulates missing time
• After 30 seconds of continuous missing checks → removes from DB
• Resets if the block becomes a hopper again, or the chunk unloads
• Re-checks immediately before delete (avoids race if someone places a hopper in that window)
• Logs one line to console when lazy prune removes a ghost

After WorldEdit moves involving wifi hoppers, staff should fly the affected area (load chunks) and run /hopper trim. Lazy prune will catch ghosts over time as players pass through loaded areas.
