Struct PendingWindowCreation 

pub struct PendingWindowCreation {
    pub label: String,
    pub kind: WindowKind,
    pub parent_instance_id: Option<String>,
}

Phase B.5 (window_meta step d) — pre-create handoff. Caller (drag.rs::tear_off, commands/window.rs::open_new_window, window_pool.rs::spawn_pool_window, pane/creation.rs) pushes one entry per window CEF is about to create; client.rs::on_after_created pops the head entry and uses kind for the Subwindow taskbar-hide branch + as the payload for ReportWindowOpened.

Replaces the previous pending_window_labels: VecDeque<String> queue + parallel caller-side window_meta writes that used to act as the kind/parent channel. Collapsing them into a single tuple eliminates the parallel-write race; on_after_created performs the single canonical window_meta.insert from the popped entry (kept as a synchronous host-side cache for open_subwindow’s parent liveness check + cascade-close enumeration in task dev mode where launcher IPC is absent).

Fields
