feat(addons): hemp plant, wild cherry tree, naturalist-lite

New addons:
- hemp-addon: silverlabs:hemp_crop (5 ages, indoor sun-lamp grown vs
  outdoor sky-lit), shears harvest, cauldron tincture, brownie food,
  bonemeal, sun-lamp redstone-lit block (light_dampening: 0 so crops
  beneath stay lit), grass-seed bootstrap, wandering-trader buyback,
  pillager raid stealing.
- trees-features-addon: ods_orch wild cherry tree — log/leaves/planks/
  stripped/sapling/fruit blocks with seasonal fruit states, structure-
  spawn worldgen.
- naturalist-lite-addon: 13-mob subset of Naturalist (deer, fox, owl,
  skunk, snake, hedgehog, red panda, capybara, elephant, kangaroo,
  moose, tiger, firefly), trimmed for Switch joinability.
