UI labels mixed part and piece terminology, several messages left asset and file names unquoted, and Blender preferences contained British spellings and typos.
Use piece terminology throughout displayed text, quote names and paths in messages and tooltips, and standardize US English spelling. Keep status-bar names and the properties-dialog title unquoted. Update translation source keys while preserving existing translations, settings keys, and external format names.
Validation: macOS Qt 6.10 Debug build passed without warnings; XML, translation-key, placeholder, and whitespace checks passed.
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.
Use PieceData consistently for the shared part/model record, its related
APIs and variables, and its source files. Keep the existing reference
counting and loading behavior so ownership and readiness changes can be
reviewed separately.
