Preserve legacy Mineralogy upgrades on Forge 26.2

[SkyBlade1978]

Summary

• preserves generated Mineralogy worlds from the published 1.10.2, 1.12.2, and 5.x configuration lineages, using saved mod metadata and world-profile precedence
• writes atomic, idempotent OreSpawn and per-world Mineralogy upgrade reports while leaving source configs and existing chunks unchanged
• qualifies existing OreSpawn 4.0.5 global/world profiles without altering Custom values or provider definitions
• adds runtime log/crash scanning and a Forge 65 dynamic-water fresh/reload gate
• keeps OreSpawn at 4.0.6 with API 1 and schemas 4/6/5 unchanged

Validation

• 119 tests across 28 suites
• 38 structured resources parsed; 16 locales with 359 keys each
• Java 25 / Gradle 9.5 / ForgeGradle 7: clean build, Javadocs, fresh/reload surface gate, and genEclipseRuns
• dynamic fluid reproduced 113 placed blocks after reopening the exact save; runtime logs were clean
• main, sources, and Javadoc jars audited with no fixture, oracle, test, or world leakage

The remaining gate is a quick player/UI test before merge.
