HopperSleeper

HopperSleeper reduces server tick load by stopping idle hoppers from polling every tick.

When a hopper is empty and has nothing to pull, it is put to sleep.
The hopper is woken instantly when a real vanilla event occurs, such as:

• an item entity entering the hopper area
• a container above changing contents
• items being inserted into the hopper

This preserves vanilla behavior while removing unnecessary block entity work.

Improvements

• Lower MSPT in hopper-heavy worlds
• Reduced tick-time spikes
• More stable TPS on servers and singleplayer

Note: tested in a superflat, peaceful difficulty world with over 100 hoppers present.

The mod does not add blocks, items, or configs, and does not modify world data.
It only changes how often idle hoppers run their logic.
