A nested guest was still getting the host -> guest 'virtual' edge, which
loops out of the container box and back into it — the screenshot on #399.
Being inside the box already says the host runs it.
Both entry points drop the link only for guests they actually nest: the
import modal path skips the edge in App's handler, and the inventory path
filters the host <-> guest pairs out of the edges bulk-approve returns.
Linked mode, loose guests and cluster edges are untouched.
