Cloud asset library and the import overhaul

Library tab#

• Cloud-only library with a category tree (3D / 2D / Misc) and drill-in browsing; category switches are instant thanks to a session cache.
• Share what you make. Publish models, terrain textures, items and NPCs (as definition bundles with their linked models), playable map bundles, interfaces and audio to the cloud. Map sharing supports replace from the map's right-click menu.
• Pulled assets are true references: one copy lives in a shared machine store and no files are added to your project.
• Library cards use a flat-at-rest hover design with a single click target and a creator line.

Import#

• Threaded import pipeline with a pre-import screen (name, type, texture size cap — the 4096 option was dropped).
• Every imported .gltf / .glb becomes a self-contained compressed .scn; the source is removed so it cannot be packed twice.
• Magenta materials on .scn loads fixed by using the engine's threaded loader.

Assets tab#

• Pop-out window for the asset browser.
• Linked model folders: drop a folder to browse it in place and add models to the project only when you use them.
