PROVEN 26.2 TRIGGER ROLLOUT
- Quarry proof chain retained exactly as proven in-game.
- Excavator mining now uses completed minecraft.mined block statistics.
- Excavator uses modern held-enchantment matching and modern `if items` drop matching.
- Removed Excavator's old hit_block marker path.
- Harvester crop-breaking now uses completed minecraft.mined crop statistics.
- Removed Harvester's old minecraft.used:<hoe> polling path.
- Harvester crop drops now use modern `if items` matching.
- Shovel path creation and hoe right-click harvesting/tilling retain minecraft:item_used_on_block,
  with the already-proven modern held-enchantment level reader.

This rollout still requires in-game confirmation for Excavator and Harvester.
