## Summary
Fixes the Cloud-only nested subgraph missing-model false positive
covered by the stacked regression test in #11907.
When returning from an outer subgraph to the root graph, the Vue graph
node manager replays `onNodeAdded` for existing graph nodes. The
realtime error-clearing hook handled a subgraph container by recursively
scanning all interior nodes. For nested subgraphs, that also scanned the
nested subgraph container itself.
Nested subgraph container widgets are promoted synthetic views of
interior widgets. Scanning them as real model-loader nodes is wrong: the
container node type is the subgraph UUID, not `UNETLoader`, so Cloud
asset resolution can classify an installed promoted model as missing.
## Changes
- Skip nested subgraph container nodes during parent subgraph replay
scans.
- Keep scanning real active interior leaf nodes.
- Add unit coverage proving the replay scan visits the `UNETLoader` leaf
but not the nested subgraph container.
- Remove the `test.fail()` annotation from the Cloud E2E regression test
added in #11907.
## Stacked PR
This PR is stacked on #11907. After #11907 lands, this branch should be
rebased or retargeted onto `main`.
