MMD OreSpawn

Updates to 4.0.6.116051

Target: Minecraft 1.16.5 / Forge 36.2.34
Functional version: 4.0.6
Complete target-qualified version: 4.0.6.116051

• 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.
• Ports the 4.0.6 feature set to Minecraft 1.16.5 using Java 8 while retaining public contracts.
• Fixes provider top, filler, underwater, and ceiling material placement and preserves trees, vegetation, structures, and block entities.
• Preserves exact datapack-biome rules, staggers close Stable Layers boundaries, and recalibrates Edge Detail and managed vanilla-ore defaults for 1.16.5.
• Retains later deep-aquifer fields as inactive data and adapts configured-feature and biome-source registration to Forge 36.
• Existing chunks are not rewritten; fixes apply as new chunks generate.
• This is functionally equivalent to the other OreSpawn 4.0.6 ports; target-only adaptations differ where later platform features are not applicable.
