AddHeads

1.1.0

• Added a public AddHeads API with service registration through Bukkit ServicesManager.
• Added reusable API models for render targets, render options, output formats, and skin textures.
• Added API events for plugin reloads and resolved skin updates.
• Added richer export formats for both the public API and PlaceholderAPI.
• Added format-aware placeholders such as format_*, chat_*, and tab_*.
• Reworked spacing after heads into configurable spacing counts instead of simple on/off toggles.
• Added separate spacing and shadow defaults for chat heads and player-list heads.
• Unified the cache refresh cycle so one configurable interval now drives skin cache refresh and player-list head reapplication.
• Added a confirmation flow for update downloads, with chat confirmation before queueing the file into plugins/update.
• Moved GitHub and Modrinth release sources into the plugin itself and left only the update-check enable/interval settings in config.
• Reworked premium detection to support auto, auto_permission, and permission modes without plugin-specific premium hooks.
• Preserved premium player preferences across joins and only apply premium defaults when a player transitions into premium state.
• Updated documentation to describe AddHeads as a universal head provider for chat, player lists, placeholders, and third-party integrations.
