3//! Wire method: `tree:getChildren`.
4//! Renderer-side tree-view child lookup. Mirrors the Cocoon→Mountain
5//! `GetTreeChildren` gRPC path but is invoked directly by the Wind/Sky
6//! tree-view bridge so the UI can request children without waiting for
7//! Cocoon to ask first.
8//!
9//! Waits up to 5 s for the Cocoon gRPC connection (boot-race guard) then
10//! dispatches `$provideTreeChildren` with a 5 s timeout. On timeout or
11//! extension rejection the workbench receives `{ items: [] }` and schedules
12//! its own retry when the view scrolls back into view.
