FRITZ'S RPG: BLACK CROWN 0.6.1 — GECKOLIB 4.9.2 FIX

INSTALLATION
1. Remove Fritzs_RPG_Black_Crown_0.6.0.jar completely.
2. Keep GeckoLib NeoForge 1.21.1 version 4.9.2 installed.
3. Install only Fritzs_RPG_Black_Crown_0.6.1_GeckoLib_4.9.2_Fix.jar.
4. Restart Minecraft completely.

TEST
/function fritzsrpg:bosses/summon_durnan

EXPECTED
- Durnan renders without NoSuchMethodError.
- The GeckoLib model appears.
- Idle/walk/attack animations initialize.
- Boss bar, music, phases, attacks and drops remain functional.

The 0.6.0 crash was caused by a manually generated compile stub that emitted
AnimationController(Object, String, int, Function). GeckoLib 4.9.2 requires
AnimationController(GeoAnimatable, String, int,
AnimationController.AnimationStateHandler).
