Replace manual piece-data retain/release bookkeeping with shared copyable asset-reference handles. Pieces, models, selection, minifigs, thumbnails, and stored insertion previews retain their dependencies explicitly, while transient queries continue to borrow pointers. Separate registered lookup and acquisition from asynchronous load requests and explicit readiness waits. Keep loader-held references through work and notification delivery, resetting shared request handles on the UI thread and guarding callback-triggered library teardown. Validated with the Qt 6.10 debug build and 26 offscreen lifecycle checks, including cancellation, stale requests, copy/move operations, model/preview teardown, undo, project merge/export, and loader shutdown.
