JujutsuTraits 2.0.0

Combined Traits, Shikigami and Mollyanna release.
Mollyanna natural spawning: 0.001% (1 in 100,000) per eligible natural
hostile-mob arrival, subject to collision and spawn checks.
Eggs, spawners and loaded mobs do not trigger replacement rolls.
Killing Mollyanna awards all ten trait advancements, including Custom Trait.
All merged custom-trait, command-editor and rendering-fix features retained.
Install the same JAR on client and server; replace older JujutsuTraits JARs.
Keep required dependencies. Do not also install standalone Mollyanna.
Network protocol remains 10; dependency versions are unchanged.

Validation: patched spawn denominator checked in compiled bytecode;
archive integrity and preservation of other compiled classes checked.
This release has not been run in Minecraft.
Bundled historical source and validation records describe earlier builds.
