RuinedStructures999

New Features:

• Added a structure overlap prevention radius system to stop new ruins from spawning too close together.
• Added per-structure world toggles using allow-lists and block-lists for world-by-world control.

Changes:

• Reload now refreshes active spawn rules and world toggle settings immediately.
• Structure list and info command output now reflects the current world context.
• Main command metadata now matches all supported subcommands.

Fixes:

• Fixed haunted graveyard generation so it can spawn correctly.
• Fixed piglin village path placement so paths generate on terrain reliably.
• Fixed fallback loot coverage so every structure type has default loot behavior.
• Fixed container loot-tracking persistence so loot state survives server restarts.
• Fixed non-player handling for force-spawn commands with clear feedback.
• Fixed legacy trap validation behavior in desert temple ruins.
• Fixed command permission gating that incorrectly blocked non-reload subcommands.
