V1.12 - Major bugfixes — LIT Creature Forge Steam update #6490709

Major bugfixes, more interesting creatures should now possibly evolve. The rest-pose pass measured phantom/rejected limbs and omitted child scale factors. Some creatures therefore spawned too high and received an artificial falling impulse. The dry build now matches actual overlap rejection, mirroring, traversal order, and segment limits Mirrored descendants were counted incorrectly during seed viability checks. Both mirrored subtrees are now traversed in true build order. The in-memory fallback limit now matches the documented 40 segments. Added a reusable morphology and physics audit.
