test(cmd-j): cover restored browser recency in the ownership regression

The same unifiedTabsByWorktree map that establishes host ownership also
feeds lastActiveAt, which orders Open Tabs and renders the row's session
age. That half of the fix had no coverage, so assert it alongside the
execution host.
