Iron Golem Poppy Luring

IronGolemPoppyFeature is an independent feature configured by the top-level iron-golem-poppy section. It has no dependency on Rotten Flesh items or their data pack and can be enabled, disabled, and reloaded on its own.

The feature uses Paper's normal Pathfinder. Candidates are limited to players holding a Poppy in their main hand and golems inside the configured range. Existing targets prevent luring, and an EntityTargetLivingEntityEvent immediately releases a lured golem when combat AI acquires a target.

The closest player wins initially. An existing leader is retained until another player is at least the configured switch-advantage blocks closer, preventing rapid target oscillation. Pathfinding is recalculated according to update-ticks, which defaults to 10 ticks.

Manual testing should cover natural and player-built golems, combat priority, hostile player targets, multiple players and golems, removing the Poppy, moving out of range, teleport, world change, disconnect, and chunk unload.
