fix(addons): silence boot-time warnings on naturalist + dynamite

- naturalist-lite: add stub item definitions for silverlabs_nat:frog_leg,
  cooked_frog_leg, snake_egg_block. Owl + snake behaviour files
  reference these but they were never defined, so BDS logged "Unknown
  item during Deferred ItemDescriptor resolution" on every boot. Stubs
  are functional — frog_leg restores 2 hunger, cooked 4, snake egg is
  a placeable nature-tab item. RP texture entries + lang strings added
  for completeness; icons fall back to candy-cane until art lands.
- dynamite: drop the broken spawn_aoe_cloud component on thrown_banger
  (its particle id "minecraft:explosion_manual" doesn't exist in BDS;
  every replacement I tried also failed schema validation). The
  random.fuse hit_sound + impact_damage still fire, the entity is
  destroyed on hit — just no lingering AOE puff.

Also: add *.bak.local to .gitignore so docker-compose.yml.bak.local and
similar local backup files stop showing up in git status.
