Advancement Rewards

A near-total rewrite — item rewards, a drag-and-drop web editor, in-game reward management, and a SQL data store.

Added

• Item rewards — grant items (with custom display name + lore via & colour codes), money, or both for any advancement. New rich config.yml form alongside the simple money-only form.
• Web editor (/ar config) — a drag-and-drop browser UI to arrange rewards and push them to the live server. Per-player session links, server-side validation of every change, and an automatic config.yml.bak backup before each apply.
• In-game reward management — /ar list, /ar advancements (browse every advancement on the server — vanilla, datapack, or mod), /ar add, and /ar remove, so rewards can be managed without editing files.
• Any advancement — vanilla, datapack, and mod/plugin-added advancements are all supported.
• Economy provider selection — choose the Vault provider (auto / Essentials / CMI / custom) in config.yml. Works without Vault for item-only setups.
• SQL player data — claim tracking moved to SQLite (default) with optional MariaDB, configured in config.yml. Asynchronous and cached so the main thread never blocks; legacy playerdata/*.yml files are imported automatically on first start.
• Multi-platform support — one jar runs on Paper, Purpur, Spigot, Bukkit, and Folia, with no extra setup on any of them.

Changed

• Supports a wide version range: Minecraft 1.18 – 26.1.2.
• Permissions reworked to ar.reload, ar.edit, and ar.admin (replacing advancementrewards.reload).
• Cleaner, paginated chat output with clickable controls for /ar list and /ar advancements.
• Improved update notifications and metrics.
