Darenfell 0.1.42.2 — Forensic Audit Hotfix

Verified corrections from 0.1.42.1:
- Corrected Nexus dimension ID in Apotheosis rarity/boss rules: nexus:nexus -> thenexus:the_nexus.
- Removed five nonexistent Simply Swords generic halberd equipment overrides.
- Removed nonexistent simplyswords:runic_halberd from the Nexus weapon reward pool.
- Split impossible Ice & Fire lightning-dragon BYG selector groups so Tropical Rainforest and Jacaranda Forest can match independently.
- Removed stale byg:windswept_valley selector branches from Desert Myrmex, Death Worm, and Fire Dragon Skeleton biome lists.
- Updated stale CurseForge manifest versionName and consolidated version-marker files.

Unchanged intentionally:
- Global Simply Swords Unique chance.
- Existing thematic/legendary hunt probabilities.
- Native mod recipes and creature loot.
- Astral Setback Apotheosis scaling (not changed until progression intent is verified).
