GetChildRowsParams

Parameters for fetching child rows of a parent node.

The context is opaque — provided by the requesting plugin and passed through to the user’s getChildRows callback verbatim. Each plugin sets a source discriminator so listeners can filter incoming child events.

Known context shapes:

• Tree: { source: 'tree', parentNode: TreeRow, nodePath: string[] }
• GroupingRows: { source: 'grouping-rows', group: GroupDefinition, groupPath: string[] }
• MasterDetail: { source: 'master-detail', row: TRow, rowIndex: number }

Child rows are fetched as a single batch — no pagination.
