First Person Model Compat

# 1.2.0 - **Punchy Compatibility:** Added optional integration for **Punchy** on Fabric and NeoForge. - **First Person Model Priority:** When Punchy is disabled, its FPM activation handler no longer blocks First Person Model body rendering. - **Animation State Restoration:** Restores Better Combat and Spell Engine first-person animation state after Punchy is disabled, preventing Punchy's already-registered hooks from keeping external animation mods suppressed. - **FPM Hide Angle Support:** When Punchy's FPM hide angle is set to `never`, Punchy is virtually disabled through its `isModEnabled` boolean while in first person, letting FPM and Better Combat animation handling keep priority. - **Mixin Safety:** Punchy mixins are gated through `CompatibilityRegistry`, use optional `@Pseudo` targets with `remap = false`, and avoid fragile Minecraft descriptors in injection annotations.
