ClickSorted 1.1.1

ClickSorted 1.1.1 adds explicit Folia support, hardens shared state for Folia's per-region worker threads, and fixes sorting from inside ClickSorted's own GUIs.

Highlights

• Explicit Folia support — the plugin now declares folia-supported and makes all shared mutable state safe for Folia's per-region worker threads.
• Lock GUI no longer sortable — sort triggers inside ClickSorted's own GUIs are now ignored unconditionally, so a click in the lock GUI can no longer rearrange its panes or the inventory beneath it.
• Atomic action throttle — the per-player throttle window is now updated atomically, closing a race under concurrent clicks.

Bug Fixes

• ClickSorted's own GUIs are never sorted — the lock GUI is a CHEST-type inventory that matched the sortable set, so a sort-trigger click inside it could rearrange its panes before the GUI listener cancelled the interaction. A ClickSortedHolder marker interface now makes the sort listener bail on any ClickSorted GUI, independent of ignore_plugin_inventory.
• The action throttle window is now atomic, preventing a race when a player's clicks arrive concurrently.

Other Improvements

• Hardened shared mutable state for Folia: CooldownMessenger's cooldown map is now a ConcurrentHashMap (keyed by player UUID), GroupsConfig mappings are built locally and swapped atomically on reload, and ItemsConfig/MainConfig reload swaps are published via volatile.
• Dropped the obsolete SWAP_OFFHAND offhand-reset workaround — modern Paper's inventory ack/sequence system reconciles the client prediction, so cancelling the event suffices. This removes the plugin's only getScheduler() call; an integration test pins the contract that a SWAP-triggered sort leaves the offhand untouched across a tick.
• Replaced plugin.yml with paper-plugin.yml.
• Avoided InventoryView method calls from plugin bytecode in LockGuiListener (using InventoryEvent.getInventory()), preventing IncompatibleClassChangeError across 1.20.6/1.21.
• MessageUtil now takes an Adventure Audience instead of CommandSender, making the Adventure routing explicit and allowing any audience to be passed.
• Made item-name lookup a pure read and removed test-only public methods with no production callers.
• Added a GitHub Actions CI workflow that runs the test suite on PRs (Java 25, matching the Paper API requirement).
