WIP: initial epic fight core extraction (Phase 0)

83 files forkés d'Epic Fight (~18k LOC). Base non-compilable en l'état.

Contenu extrait :
- math/ — OpenMatrix4f, Vec3f/4f/2f, QuaternionUtils, MathUtils, ...
- armature/ — Armature, Joint, JointTransform, HumanoidArmature
- anim/ — Animator, ServerAnimator, ClientAnimator, LivingMotion, ...
- anim/types/ — StaticAnimation, DynamicAnimation, MovementAnimation, LinkAnimation,
                ConcurrentLinkAnimation, LayerOffAnimation, EntityState
- anim/client/ — Layer, ClientAnimator, JointMask
- mesh/ — SkinnedMesh, SingleGroupVertexBuilder, Mesh, HumanoidMesh, ...
- cloth/ — AbstractSimulator, ClothSimulator (dépendance transitive de StaticMesh)
- asset/ — JsonAssetLoader, AssetAccessor
- patch/ — EntityPatch, LivingEntityPatch, PlayerPatch, ClientPlayerPatch
- util/ — ParseUtil, TypeFlexibleHashMap
- exception/ — AssetLoadingException
- event/ — PatchedRenderersEvent, PrepareModelEvent, RegisterResourceLayersEvent
- render/ — TiedUpRenderTypes

Headers GPLv3 + attribution injectés sur tous les .java.
Package declarations fixées sur Armature.java et TiedUpRenderTypes.java.

115 imports résiduels à résoudre manuellement :
- yesman.epicfight.main (EpicFightMod, EpicFightSharedConstants) — 30
- yesman.epicfight.gameasset (Animations, Armatures, EpicFightSounds) — 12
- yesman.epicfight.api.physics + physics.ik (combat physics) — 16
- yesman.epicfight.network.* (combat packets) — 13
- yesman.epicfight.world.* (combat entity logic) — 10
- yesman.epicfight.config.ClientConfig — 3
- yesman.epicfight.skill, .client.gui, .particle, .collider — divers combat/UI

Stratégie fix (2-3 sem manuel) : strip usage combat, stubs pour refs
core (EpicFightMod → TiedUpMod, SharedConstants → TiedUpRigConstants,
ClientConfig → TiedUpAnimationConfig).
