This brings the 1.19.4 version to Minecraft 1.20.1 and Forge 47.4.10.

• Keep raw metals, Kiri's ore overlays, filled buckets, High/Low Fantasy modes and the earlier gameplay fixes.
• Update creative tabs, configuration screens, loot and networking for the 1.20.1 APIs.
• Fix the intermittent Forge login stall by keeping connection read changes on Netty's event loop. Login checks and timeouts are unchanged.
• Use the published OreSpawn 4.1.0.120011 release and keep the existing ore rules and copper defaults.
• Update optional integrations and keep them in a separate development profile. Normal launches still load only Base Metals and OreSpawn.
• Preserve saved block and item IDs, configuration keys and world-upgrade backups. Keep test probes and build fixtures out of the public jars.

Local checks passed: 77 unit tests, 39 GameTests, 14 comparison-tool tests, generated-data checks, dependency and jar audits, Eclipse isolation, packaged client/server runs and two byte-identical clean builds. All seven separate client/server mode checks passed, including older configs and intentional mismatches. The port's earlier qualification also covered legacy world upgrades and optional integrations, using disposable worlds. Manual testing is complete.
