PNG Stalkers v5 Window/Door Final Fix

Fixed:
1. Window Jester:
   - Touching him still triggers the attacker.
   - If you do NOT touch him, he now disappears after 20 seconds.
   - He no longer summons the attacker just because time ran out.

2. Door Jester:
   - Door still breaks and drops as an item.
   - Door Jester now spawns after the door breaks so the PNG does not vanish.
   - Door Jester position adjusted closer to the door and visible outside.

Commands:
 /function pngstalksafe:version
 /function pngstalksafe:changes
 /function pngstalksafe:test_window_door_fix
