Supported game versions

Added support for detecting pre-existing furnaces. Simply open an old furnace to automatically add it to the fast-processing list.
Added Quick Extract: Sneak + interact with a furnace using an empty hand to instantly collect all available outputs without opening the menu. If no output is available, the menu opens normally.
Added Status Particles:
- Green Circle — Smelting complete or output slot is full.
- Red Circle — Input available, but no fuel.
- White Smoke Circle — Fuel available, but no input.
- Fire Circle — Waiting for the current fuel unit to finish burning.
Added smooth, rotating loading-style particle animations.

Fixed issues with furnaces in unloaded chunks. Furnace data is now safely preserved even when traveling far away or re-entering the world.
Added automatic garbage collection: furnace data inactive for 30 days is removed to prevent save bloat and long-term server lag.
Corrected the tick interval from 20 to the intended 40 ticks.
Significantly optimized Dynamic Property storage by saving only interaction timestamps and writing data only when changes occur.
Fixed stack limit handling to correctly respect each item's maximum stack size.
Fixed output type validation to prevent different items, such as gold and iron, from being combined.
Fixed the fuelValue < 1 scaling logic to prevent fuel loss and fuel-processing stalls.
