WIP: create TiedUpRigConstants, replace EpicFightMod/SharedConstants refs

- Nouveau TiedUpRigConstants.java : centralise MODID/LOGGER/identifier/prefix,
  constantes runtime (IS_DEV_ENV, A_TICK, GENERAL_ANIMATION_TRANSITION_TIME,
  MAX_JOINTS), factory ANIMATOR_PROVIDER (client/server split) + helpers
  stacktraceIfDevSide/logAndStacktraceIfDevSide.

- sed global : EpicFightMod.* → TiedUpRigConstants.*
- sed global : EpicFightSharedConstants.* → TiedUpRigConstants.*
- sed global : EpicFightRenderTypes → TiedUpRenderTypes (class rename upstream)
- Fix package declarations : Armature.java + TiedUpRenderTypes.java

Résidus yesman.epicfight : 115 → 86 (-29)
Reste : gameasset/physics/network/world/config/skill (combat deps à strip) +
combat mode refs dans patch/LocalPlayerPatch + ClientPlayerPatch (Phase 2).
