Quick Stack Inventory

Initial Release

• Added Quick Stack keybind (default: V): Automatically moves items from your inventory into nearby containers that already hold matching items, within a configurable radius
• Added Misc Inventory system: Assign any container as a misc inventory with 'V + Right Click'. 'Shift + V' or 'Shift + inventory button' dumps remaining inventory items into the nearest assigned "misc inventory" in range
• "Misc inventories" are last in prioirty for normal quick stack. When a player dumps their inventories the free spaces in Misc inventories are used to deposit the nonmatching or overflow items in a players inventory.
• Added Quick Stack button in the player inventory screen with configurable position in config.
• Added flying item animation — items visually fly from the player to the target container, with a chest open/close animation
• Added config file (quickstack-common.toml) with options for scan radius, minimum container slots, and button position
