Fix natural rock compatibility on Minecraft 1.18.2

[SkyBlade1978]

This brings the natural rock compatibility fixes to Minecraft 1.18.2 Forge as Mineralogy 6.1.4.118021.

• Moss, dripstone, azalea roots and forest rocks recognise natural Mineralogy terrain. Goat spawning works on it too.
• Slabs, stairs, walls, raw rocks, ores and storage blocks have the matching vanilla and Forge tags. Normal cobblestone follows the existing config option.
• Rock-salt lamps keep the wall post beneath them. Disabled construction forms no longer leave missing tag or loot references.

Natural decoration changes apply to newly generated chunks. Goat spawning works in existing worlds. Polished and crafted blocks stay outside the natural terrain rules; bare rock is not azalea tree soil.

Recipes, registry IDs, configs, provider data, migrations, textures and the released OreSpawn dependency are unchanged. README and changelog are current, and the version guide no longer says publication is paused.

Validation: 73 tests, two reproducible clean release builds, jar and dependency audits, Javadocs and production-only Eclipse launch checks. The accepted candidate also has retained loader/reload, paired cave-generation and packaged client/server test evidence. Release preparation changes only documentation; every other jar entry matches that candidate.
