Sky World

Requires Isekai API 2.2.0.

Fixed

• Islands below the topmost one in a column now get ore and stone variants too. ore_strategy previously resolved only against the highest island in a stacked column, so anything floating above a lower island left it with no ore at all.
• Amethyst geode exposure is back to its previous level. Isekai API 2.2.0's fix above increased geode exposure 1.797x as a side effect; rarity_filter is retuned (160 -> 288) to cancel it out.

Added

• Below island depth 12, stone turns to deepslate variants (isekai_api:strata) - deepslate ores generate there instead of the regular ones.
