Summary
Fixes a model install startup race where a new import could be enqueued before incomplete installs had finished restoring.
The model install service now tracks the startup restore thread with an event and waits for restore completion before accepting new imports or reporting install completion. This prevents duplicate or conflicting install work during app startup.

Run
