Immersive Weathering: Renewed

Patch release on top of V1.0.0. All runtime regressions surfaced during V1.0.0 play - both standalone and inside a 95-mod modpack - are fixed.

What's new in V1.0.1

• Recipes - migrated all 349 IW recipe JSONs to the 1.21 ingredient object format. Crafting holes for waxed iron, mossy bricks, leaf piles, charred wood, and more are gone.
• Sapling, flower, and bush placement on IW soils now works under modpacks that ship "replace": true overrides of vanilla minecraft:dirt (e.g. Still Life). Implemented as a defensive IW-namespaced fallback tag.
• Dead bush, bamboo (stalk + sapling), and sugar cane placement on Earthen Clay, Silt, Sandy Dirt, Permafrost, Rooted Grass, and grassy variants. Sugar cane requires water adjacent below, mirroring vanilla.

Required dependencies, license, and known divergences from upstream are unchanged from V1.0.0 - see the V1.0.0 changelog or META-INF/PORT_NOTES.md inside the jar for those.
