MGS Origins Expanded 3.1.0 — Animation Combat

Epic Fight integration for Minecraft 1.20.1 Forge / Epic Fight 20.14.17.

Enabled weapon animation overrides:
- efn:hf_blade -> Epic Fight Tachi moveset
- efn:hf_murasama -> Epic Fight Uchigatana moveset

This reuses Epic Fight's built-in animations; the MGS jar does not redistribute Epic Fight assets.
The built-in movesets provide combo attacks, dash attacks, air slashes and weapon living motion.

Gameplay intent:
- Raiden / Gray Fox: HF Blade uses fast two-handed blade flow from Epic Fight Tachi style.
- Jetstream Sam: HF Murasama uses the Uchigatana/katana-style motion set.
- Existing vanilla Epic Fight weapon animations remain untouched for all other items.

Important: Epic Fight's 1.20.1 documentation states that a weapon capability under data/<item_namespace>/capabilities/weapons/<item>.json
can assign a weapon type, and the type controls its animations. The docs also require at least combo, dash and air-slash animations for a functional moveset.
