Update Forge 1.20.1 to OreSpawn 4.0.16

[SkyBlade1978]

Summary

Updates the Forge 1.20.1 branch to 4.0.16.120011 and carries the five fixes tested on the preceding Forge branches:

• align public geology sampling with the highest occupied surface block;
• expose ore-dimension biome include/exclude filters and accept namespaced geome IDs in both editor paths;
• convert exposed one-layer snow at top + 1 without touching buried or authored weather blocks;
• use one direct quart-biome lookup for generation and sampling so biome-family host attribution remains stable;
• let Forge's GameTest harness own benchmark reporting and shutdown while retaining ordinary dedicated-server auto-stop.

The existing API major, schemas, registry IDs, profile formats and migration behaviour remain unchanged. Existing chunks are not rewritten.

Validation

• 134 tests across 33 suites, with no failures or skips;
• 40 JSON/mcmeta files, 16 locales with 359 matching keys, and all 21 documentation exports verified;
• full offline build, Javadocs, release-artifact and Eclipse/Buildship gates;
• cold exact-commit build with byte-identical main, sources and Javadoc artifacts;
• empty-cache Forge bootstrap with all eight compatibility rules and idempotent reload;
• userdev and exact packaged Forge fresh/reload servers plus launcher-like packaged client;
• dynamic-biome ore/family attribution, snow/ice, preferred-seed and benchmark gates;
• no material performance regression and clean runtime/crash scans.

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