v2.0 — Complete rewrite: Clone Satori + Nehan instead of building from scratch

Key changes:
- Katana:  Items.Preset_Katana_Saburo_Legendary (Satori clone)
  → Retains all bleeding, hemorrhaging, hidden GameplayLogicPackages
- Knife:  Items.Preset_Tanto_Saburo_Retrofix (Nehan clone)
  → Retains thrown bleeding, hemorrhaging, health restoration
- Only displayName/localizedDescription overridden
- Localization in r6/loc/en-us/ and r6/loc/de-de/ (proper LocKey resolution)
- Removed all custom statModifiers (they were ignored anyway)
- Removed IconicWeaponModAbilityBase approach
- Removed LocalizationOverride block
- Clean file structure matching CDPR conventions

Thanks to ChatGPT for the correct approach:
- Stats via statModifiers were being ignored
- HealOnKill/HealthRegen don't exist as BaseStats
- Nehan heals via GameplayLogicPackage, not stats
- ArmorPenetration is not the right stat name post-2.0
- Cloning existing Iconics preserves all hidden behavior
