Swift Harvest Datapack, Crops Replant Themselves

Complete rewrite. Version 1.0 did not work at all.

The old version's folder was called funktions and its files ended in .mcfunktion; Minecraft only reads function/ and .mcfunction. It had no function tags, so nothing would have started even with the right names, and its tool check used an NBT path called Dimensions that does not exist. A test server reported Unknown function harvest:tick.

What changed about the idea, and why

The original promise was right-click harvesting. That is not possible in a datapack. A datapack can only react to events the game reports, and right-clicking a crop in vanilla does nothing at all, so nothing is reported. Verified on a real 26.2 server with a real mouse click against every candidate advancement trigger (item_used_on_block, any_block_use, default_block_use): placing a torch on stone fires two of them, right-clicking ripe wheat fires none. That is why every "right click harvest" project on Modrinth is a mod.

2.0.0 hooks the moment that is reported - the harvest itself:

• Break a grown crop and it is replanted immediately
• Exactly one item from the drop is used; you keep the rest
• Wheat, carrots, potatoes, beetroot and nether wart
• Any tool or bare hands; Fortune still works normally
• No farm scanning and no per-player raycast - the pack only looks at dropped items, so an idle server does no work

Tested on real servers on 1.21.11, 26.1.2, 26.2 and 26.3 pre-2, every crop checked individually, including that the seed count goes down by exactly one.
