/**
* `<lr-approval-queue>` — a controlled queue of tool calls that need human approval, with a
* keyboard-accessible request list and a single reused `<lr-tool-approval-dialog>`. It never
* executes tools, applies permissions, or persists decisions; the host owns those operations.
* Empty request ids are omitted and duplicate ids normalize before counts, selection, rendering,
* and events; the first valid occurrence wins.
*
* Public collection properties take bounded, clone-owned readonly snapshots. Create a new
* collection and reassign it after changes; mutating the assigned array does not update the view.
*
* @customElement lr-approval-queue
* @event lr-approval-select - A request was selected. `detail: { invocationId }`.
* @event lr-approval-decision - A request was approved or denied. `detail: { invocationId,
*   approved, args? }`. Cancelable; preventing it keeps the nested dialog pending.
* @event lr-approval-close - The nested decision dialog closed, or controlled requests invalidated
*   its formerly pending selection. `detail: { invocationId, reason }`; invalidation uses
*   `reason: 'request-invalidated'` after selection and open state are cleared. Non-cancelable.
* @csspart base - The root queue wrapper.
* @csspart heading-row - The heading and pending-count row.
* @csspart heading - The visible queue heading.
* @csspart count - The pending-count text.
* @csspart list - The request list.
* @csspart request - One selectable request row.
* @csspart request-info - Request name and id wrapper.
* @csspart tool-name - The proposed tool name.
* @csspart request-id - The stable request id.
* @csspart status - The request status badge.
* @csspart empty - The empty state.
* @cssprop [--lr-approval-queue-selected-border=var(--lr-color-brand)] - Selected request border.
* @status stable
* @since 6.2.0
