Idle Generators

Hotfix: achievements stay enabled!

Idle Generators no longer disables achievements. Both packs now declare the product_type: addon manifest flag, so applying the addon to a world keeps achievements fully working (as long as the world itself qualifies: no cheats, no experiments, not loaded in Creative).

Notes:

• Only protects worlds where achievements are still enabled. If a world already had achievements disabled by a previous version, that flag is permanent for that world (Minecraft behavior, not fixable from the addon) — start a new world or transfer your progress.
• No gameplay changes; safe drop-in update from v1.2.0.
