1.1.0

• Essential Compatibility: Added optional integration for Essential cosmetics on both Fabric and NeoForge.
• First-Person Cosmetic Hiding: Essential head-related cosmetic slots now respect ignoredAccessorySlots, hiding them only while FPM renders the local player's body in first person.
• Integration Registry: Centralized runtime bridge initialization and optional mixin detection in a shared CompatibilityRegistry, so startup diagnostics and mixin gating now use the same source of truth.
• Detection Fixes: Corrected Combat Roll package detection for current versions and improved optional mixin detection for loader-specific integrations and Essential's staged loader.
• Mixin Stability: Moved the Essential integration to the common mixin config with an optional @Pseudo target and remap = false, avoiding hard runtime/build dependencies when Essential is not installed.
