SimpleWand

Added

• Axiom-style creator menu opened with TAB.
  • 9×9 grid of hotbar pages (vanilla hotbar texture per row, 1px white outline marks the active page).
  • Scroll wheel inside the menu switches active page; mouse click on a row also switches.
  • Fly-speed slider (range 10%–500% of the vanilla 0.05 flying-speed, default 100%).
  • Gamemode buttons: Survival, Spectator, Adventure.
  • Opening the menu auto-runs /gamemode creative for OPs (no Creative button needed).
  • Layout auto-centers regardless of window size; slider sits to the right of the centered grid; buttons centered above grid.
• Extra wand slot right of hotbar slot 9.
  • Cyclic scroll: scrolling past slot 9 enters the wand slot, scrolling again wraps to slot 1; both directions cyclic.
  • Wand item is wooden axe by default, persists in world NBT (world/data/simplewand_wand_slots.dat) per UUID.
  • Server-authoritative item swap: activating the wand stores the previous slot item, places the wand in the active inventory slot; deactivating restores it.
  • Auto-deactivation on number-key press, gamemode change to non-creative, or player logout.
  • Client-only render: extra slot only visible in creative (hidden in survival, adventure, spectator).
• Render fixes via Mixin (Gui mixin):
  • Vanilla hotbar's selected-slot highlight is hidden while the wand is active (selector now sits on the extra slot only).
  • The original item at the active slot continues rendering in slot 9 (or wherever the wand was activated from), so it never appears blank or shows the wand-axe in two places.
• Networking: 3 packets via Architectury NetworkManager — ACTIVATE_WAND (slot), DEACTIVATE_WAND, SYNC_WAND (ItemStack).
• NBT-persistent wand storage via WandSlotData extends SavedData on the overworld DimensionDataStorage.
• TAB keybind registered via KeyMappingRegistry (overrides vanilla player-list while in creative menu mode).
