Immersive Weathering: Renewed

Port of Immersive Weathering by Ordana, MehVahdJukaar, and Keybounce, brought up to Minecraft 1.21.1 / NeoForge. Upstream baseline: 1.20.1-2.0.5 (LGPL-3.0).

Verified in play

• Iron rusting on land and in water
• Moss spread on stone, cobblestone, brick, and stone-brick families
• Sapling, flower, and bush placement on Rooted Grass, Earthen Clay, Sandy Dirt, Silt, Permafrost, and the grassy variants
• ✨s (crop) growth ticks (NeoForge CropBlock.getGrowthSpeed signature divergence from vanilla handled — would have crashed on first chunk tick)

Known divergences from upstream (1.20.1)

These are intentional regressions taken to keep the port shippable; each is a candidate for a follow-up patch release:

• Custom particle network packets are no-op. Leaf-decay and similar client-side particle effects are not pushed from server to client. Block state changes, sounds, and gameplay-affecting behavior are unaffected.
• Per-item fuel times are no longer registered in code. They now live in data/<modid>/neoforge/fuels.json. Existing burnable items fall back to default behavior unless redeclared via datapack.
• IcicleItem / IceSickleItem are no longer edible and IceSickleItem no longer applies custom sword damage values. Both are wired through 1.21 data components and need to be re-enabled at registration.
• Trident channeling check simplified in FulguriteBlock: lightning triggers on any trident hit during a thunderstorm rather than specifically channeling-enchanted hits.
• Data-driven block-growth / fluid-generator / position-rule-test systems are inert. The Codec.dispatch chains were stubbed during the port pending a MapCodec migration. Existing JSONs in those directories are parsed but not applied.
• Charred projectile interaction is a no-op.

See META-INF/PORT_NOTES.md inside the jar (or the GitHub repo) for full technical detail.
