Our own emote library to replace player-animation-lib, which doesn't support the newer versions or limb bending. This PR is only the scaffold. Bending comes next.

What's here

core/: animation model with no Minecraft dependency: Bone, BoneTransform (it already has bend/bendAxis fields), Pose, Animation, AnimationPlayer. Includes JUnit tests.
src/main: the Fabric mod, built for 1.21.4–1.21.11 with Stonecutter on Mojang mappings.
- LivingEntityRendererMixin samples each player's pose into the render state.
- HumanoidModelMixin applies it at the end of HumanoidModel.setupAnim, so armor follows the pose too.
- Both hook points are the same in every supported version, so there are no version branches yet.
src/testmod: a dev-only tester that isn't published. It adds /emotes play <wave|tpose|bob|bend>, /emotes stop and /emotes info, and runs a Mixin audit at startup so a broken target fails right away.
Publishing: goes to the saturnclientmc Gitea registry as org.saturnclient:emotes-core and org.saturnclient:emotes-fabric:<v>+<mc>, with core bundled inside the jar.

Testing

./gradlew :core:test passes.
./gradlew buildAll builds all 8 jars, and the mixin targets are remapped to intermediary.
runTestmodClient starts on all 8 versions and the mixin audit passes. I haven't played an emote in a world yet.
publishToMavenLocal produces the expected POMs. Nothing is published to Gitea yet.

Notes

Loom is pinned to 1.17.21 because 1.18 needs a Java 25 JVM to run Gradle. 26.x will need that upgrade.
BoneTransform.bend isn't rendered yet.

- core/: Minecraft-independent animation model (Bone, BoneTransform with
  bend fields, Pose, Animation, AnimationPlayer) with JUnit tests.
- src/main: Fabric mod built for 1.21.4-1.21.11 with Stonecutter on
  Mojang mappings. Samples each player's pose into its render state and
  applies it at the end of HumanoidModel.setupAnim (armor follows too).
- src/testmod: dev-only tester with /emotes play|stop|info and a mixin
  audit on startup.
- Publishing to the saturnclientmc Gitea Maven registry as
  org.saturnclient:emotes-core and emotes-fabric:<v>+<mc>.

Loom is pinned to 1.17 because 1.18 needs a Java 25 JVM.
