Port OreSpawn 4.0.16 to Forge 1.19.4

[SkyBlade1978]

Summary

Ports the tested OreSpawn 4.0.12-4.0.16 campaign from Forge 1.18.2 to Forge 1.19.4 and finishes at 4.0.16.119041.

• aligns the public sampler's first-free surface height with generated geology;
• adds immutable ore-dimension biome include/exclude and dictionary filters to the public provider builder while retaining the existing schema fields;
• accepts both canonical namespaced and legacy geome IDs in the editors;
• converts exposed one-layer snow at top + 1 without touching buried or authored snow/ice;
• gives generation, managed ores and the public sampler one direct quart-biome attribution path;
• leaves GameTest shutdown to Forge's harness while retaining ordinary benchmark-server auto-stop.

No registry IDs, schemas, provider meanings, migration behaviour or existing chunks change. API major remains 1 and compatibility remains [4.0.6,5.0.0).

Validation

• 132 tests across 33 suites, with no failures, errors or skips;
• full offline build, Javadocs, artifact audit and Eclipse production-classpath gates;
• repeated from a clean exact-commit worktree with byte-identical artifacts;
• empty-cache Forge 45 bootstrap with all eight sealed Mavenizer compatibility rules and idempotent rerun;
• userdev and exact reobfuscated packaged-server surface fresh/reload tests;
• packaged client world creation, editor navigation, render, save and reload;
• exposed snow/ice, biome-filter, dynamic-biome ore, direct attribution, fluid and sentinel coverage;
• GameTest and ordinary benchmark lifecycle tests, preferred-seed ore audit and matched performance controls;
• all runtime logs and crash directories audited.

The exact candidate was manually tested before publication to the fork.
