Port OreSpawn 4.0.16 to Forge 26.1.2

[SkyBlade1978]

Summary

Ports the complete OreSpawn 4.0.8 through 4.0.16 campaign to Minecraft 26.1.2 / Forge 64.0.9, finishing at 4.0.16.2601021.

This includes:

• persistent long Ore and Fluid editor values;
• early, safe replacement of provider-declared natural terrain hosts;
• Stable Layers rock eligibility based on actual world Y;
• dynamic-registry biome tags and stable-key ore filtering;
• sampler surface-height alignment;
• public ore-dimension biome filter APIs and namespaced geome IDs;
• exposed Snow and surface Ice conversion;
• shared stable biome attribution for geology, sampling and family-restricted ores;
• GameTest-owned benchmark shutdown while retaining ordinary benchmark auto-stop.

Forge 26.1.2 adaptations

The port preserves Forge 64's Identifier APIs, biome bootstrap model, ChunkPos.pack(), official runtime naming and reobf=false. It retains namespaced Overworld storage with legacy-root detection, the optimized LevelChunkSection geology write when safe, four target access transformers, disjoint production-only Buildship outputs, and an explicitly zero-rule cold-bootstrap Mavenizer manifest for Forge 64.

The build/release scaffold now uses ForgeGradle 7.0.34, Gradle 9.6.1 and exact Temurin 25.0.3+9, with deterministic version-only artifacts, release audits, checksums, immutable bundle verification, guarded Maven preparation, pinned CI/wrapper/CodeQL/tag workflows, the sealed Mineralogy 5.4.0 migration oracle, and all 21 documentation exports.

Compatibility

• API major remains 1.
• Provider/global/world schemas remain 4/6/5.
• Registry IDs, provider field meanings, profile filenames and migration behavior are unchanged.
• Existing chunks are not rewritten.
• Compatibility range [4.0.6,5.0.0) remains unchanged.

Validation

Exact accepted candidate: 651299447413f549fbeaab5e7ef08b2d872532ae.

• 140 tests across 33 suites, with no failures, errors or skips;
• 41 JSON/mcmeta files parsed, 16 locales with 359 matching keys, and 21-document byte parity;
• complete offline build, Javadocs, release audit and Eclipse lifecycle;
• cold exact-commit build plus genuinely empty-cache Forge bootstrap and idempotent rerun;
• exact packaged Forge 64 client and server fresh/reload tests with clean log/crash scans;
• surface, natural-host, dynamic-biome, Snow/Ice, fluid, stable-attribution and GameTest lifecycle gates;
• preferred-seed 81-chunk generation with all eight managed ore families and no range violations;
• staged Sky/Average, Cyano and vanilla benchmark qualification below the release thresholds;
• all three release jars audited for Java 25, Forge 64 metadata, access transformers, documentation/locales and zero fixture/tool/test/world leakage.

The exact candidate was manually tested and accepted before publication to the fork. This PR does not tag, release or directly update the MMD target branch.

Hosted cold-bootstrap follow-up

Current PR head: 0d97dad89229c8e2034172239df3cdc1fb407441.

The first hosted cold-bootstrap attempt reached Forge preparation but hit a transient java.net.http.HttpTimeoutException while Mavenizer downloaded the library list. The exact empty-cache bootstrap had already passed locally. The follow-up commit adds the established bounded three-attempt download retry and a retained workflow-contract assertion. It changes only .github/workflows/ci.yml and ReleaseWorkflowContractTest; runtime code, version and public release-artifact inputs are unchanged.
