AreaScale

Major redesign from the original "resize blocks in place" concept to an item-based capture/display/placement workflow:

• Structure Capsule item: /areascale expand|shrink <factor> captures a wand-selected area (blocks, block entity data, and non-player entities) into a portable item at any scale, not just whole numbers. Captured structure data lives in world-level saved data referenced by a UUID rather than embedded directly in the item, which avoids a network packet becoming too large to decode on big captures.
• Display Platform block: place a capsule on it to show the capture as a scaled diorama (block-display entities), rotating to match the player's facing, hollowed out for performance, pickable back up into a capsule. Captured entities (armor stands, mobs, etc.) are intentionally never spawned into the diorama itself - there's no real floor for them to stand on there, so they'd just fall out or wander off - but their data is untouched in the capsule, so they're reconstructed correctly once the Structure Placer places the structure for real. Water and lava, which otherwise can't render at all through a block-display entity (their render shape is hardcoded invisible in vanilla - real fluid rendering depends on neighboring fluid levels in the world, which a floating display doesn't have), show up as translucent colored glass stand-ins in the diorama specifically; the real block is still captured and placed correctly by the Structure Placer.
• Structure Placer block: places the capture back as real blocks at its original 1:1 scale (ignoring the diorama scale), with a glowing ghost preview, collision checking, and a true fixed-pivot rotation - the structure's original captured corner stays pinned exactly at the placer for every facing, with no gap.
• /areascale undo (creative only): single-level undo of the last capture. Only frees the underlying structure data if the capsule is still untouched in the player's inventory, so undoing a capture that was already placed on a Display Platform or Structure Placer can't leave that display stuck with a dangling reference.
• Configurable capture limit (config/areascale.json, maxCaptureBlocks).
• Coordinate-editor overlay: press U (while you have both selection points set) to hand-edit the wand selection's X/Y/Z values directly, live, as real clickable buttons with a background panel for legibility - left-click +1, right-click -1, shift for +/-10 - without opening a normal pause menu, so the wireframe selection box keeps updating live behind it. Pressing U with no selection yet just tells you to select an area first instead of opening an empty editor.
• Survival crafting recipes for the wand, platform, and placer.
• Both blocks are thin, 2-pixel-tall platforms (like a pressure plate or snow layer), not full cubes - shape, collision, and visual occlusion are all explicitly overridden to match.
