Port OreSpawn 4.0.16 to Forge 1.13.2

[SkyBlade1978]

Summary

Ports the accepted OreSpawn 4.0.16 campaign to Minecraft 1.13.2 / Forge 25.0.223 and publishes version 4.0.16.113021.

This backport adds the applicable fixes from 4.0.9 through 4.0.14 while preserving Forge 1.13's static, two-dimensional biome model:

• moves the single terrain-host replacement pass to the start of LOCAL_MODIFICATIONS, ahead of provider surfaces, while preserving later authored blocks and rejecting air, fluids, bedrock and block entities;
• evaluates Stable Layers rock bounds against actual world Y while retaining shifted formation Y for layer identity and deterministic fallback selection;
• adds immutable ore-dimension biome ID and dictionary include/exclude builder/getter contracts using the existing provider JSON fields;
• accepts canonical namespaced and legacy unnamespaced geome IDs with strict target-native validation;
• converts exposed one-layer Snow at top + 1 while retaining the existing Snow/Ice scan and all buried/authored safety controls;
• records the dynamic-registry, sampler-height, 3D biome-attribution and GameTest-server fixes as target-inapplicable rather than adding compatibility facades to Forge 1.13.

The release/build work also adds the cache-cold Forge bootstrap gate with pinned Java 25/8/17 toolchains, while retaining official MinecraftMavenizer 0.5.19 with a verified zero-patch result. Existing ForgeGradle 7 release safeguards, deterministic version-only artifacts, 21-document export, exact Mineralogy 1.13.2 5.0.1 oracle, LWJGL3-only Eclipse classpath, duplicated bin/main discovery, five access transformers and the Forge 25 WorldGenRegion.isChunkInBounds fluid guard are preserved.

Compatibility

• Minecraft 1.13.2, Forge 25.0.223, MCP snapshot_20180921-1.13
• Java 8 bytecode, ForgeGradle 7.0.34, Gradle 9.6.1, pack format 4
• API major 1 and profile/provider schemas 4/6/5 remain unchanged
• registry IDs, provider field meanings, profile filenames, migrations, existing chunks and [4.0.6,5.0.0) compatibility remain unchanged

Validation

• 130 JUnit tests across 33 suites; zero failures, errors or skips
• 26 JSON/mcmeta files parsed; 16 locales with exactly 357 matching keys
• all 21 documents byte-identical across tracked, generated, Eclipse, runtime and packaged copies
• complete offline build, Javadocs, release audit, checksums and Buildship/genEclipseRuns production-classpath gate
• cold exact-commit lifecycle plus genuinely empty-cache Forge bootstrap and same-cache offline replay
• userdev and exact reobfuscated packaged Forge 25 client/server fresh and reload phases
• surface qualification covering 2,304 columns, 6,912 fillers, natural-host ordering and safety, Nether ceiling handling, weather conversion, springs, fluids and exact-save reload
• packaged client world/editor round trip preserving all eight long fields and byte-equivalent profile JSON
• preferred seed -4965128775892001975 with four configured rocks, all seven applicable managed ores in range, covered lava, Custom 77/13/2, unchanged profile/original-area hashes on reload and no decoration-region boundary error
• matched three-run 81-chunk Sky/Average, Cyano and vanilla controls remained within release thresholds
• all three artifacts audited for Java class major 52, Forge 25 metadata, SRG reobfuscation, exact access transformers, documentation/locales and zero fixture/oracle/test/world/tool leakage
