New Features

• Added permission-based order limits via donutorders.limit.<n> nodes (e.g. donutorders.limit.5, donutorders.limit.10).
• Added support for rank-specific maximum active orders through optional rank-limits configuration.
• Added PlaceholderAPI support: %donutorders_order_limit% returns the player's currently applied limit.
• Added /orders limit <player> admin command (alias: /donutorders limit <player>).

Improvements

• Added a caching system for permission-based limit lookups to avoid scanning permissions on every order creation.
• Limit cache refreshes automatically on player join, config reload, and LuckPerms permission recalculation.
• Order limit reached messages are now configurable via messages.yml.

Configuration

• Added orders.default-limit as an optional config key (takes priority over legacy orders.max-per-player when set).
• Added optional rank-limits configuration section for group-based fallback limits.
• Added messages.order-limit-reached with %limit% and %active_orders% placeholders.

Permissions

• donutorders.admin.limit — allows use of /orders limit <player>.
• donutorders.limit.<n> — grants a custom maximum active order count.
