Wire method: tree:getChildren.
Renderer-side tree-view child lookup. Mirrors the Cocoon→Mountain
GetTreeChildren gRPC path but is invoked directly by the Wind/Sky
tree-view bridge so the UI can request children without waiting for
Cocoon to ask first.
Waits up to 5 s for the Cocoon gRPC connection (boot-race guard) then
dispatches $provideTreeChildren with a 5 s timeout. On timeout or
extension rejection the workbench receives { items: [] } and schedules
its own retry when the view scrolls back into view.
