MMD OreSpawn

Updates to 4.0.6.121012

Target: Minecraft 1.21.1 / NeoForge 21.1.247
Functional version: 4.0.6
Complete target-qualified version: 4.0.6.121012

• Adopts the four-component version format so Minecraft and loader compatibility are visible in the version.
• Preserves worlds made with Mineralogy 1.10, 1.12, or 5.x and writes idempotent upgrade reports without changing source files or existing chunks.
• Audits runtime logs and dynamic-fluid generation so logged worldgen failures cannot pass silently.
• Qualifies existing OreSpawn 4.0.5 global and per-world profiles without changing explicit Custom values or provider definitions.
• Fixes provider top, filler, underwater, and ceiling material placement while preserving trees, vegetation, structures, and block entities.
• Honours exact biome-to-geome weights on dynamic biome registries.
• Staggers Stable Layers transitions by layer and recalibrates Edge Detail so Average retains natural variation.
• Existing chunks are not rewritten; fixes apply as new chunks generate.
• This is functionally equivalent to the Forge and other NeoForge 4.0.6 ports; only target-specific platform adaptations differ.
