Merge branch 'main' into feat/block-install-state

2.4.0 to 2.4.2 wrote auto_drop on each build item, and 2.4.x objects
carry no auto_drop attribute in model_settings.config. The importer only
read the object attribute and treated a missing one as on, so floating
objects were dropped to the bed on load and the flag was rewritten as on
on the next save.

Record object ids with an item auto_drop="0" and use that as the fallback
when the object has no attribute. The attribute's presence is now tracked
so the fallback applies only when it is absent. Any item set to off turns
auto drop off for the object, since the flag is shared by all instances.
