- * Provides data for the Run History treeview panel in VS Code's sidebar.
- * Implements VS Code's TreeDataProvider interface which defines how tree views are populated.
- *
- * TreeDataProvider requires two methods:
- * - getTreeItem(): Returns the visual representation of a tree element
- * - getChildren(): Returns child elements for hierarchy (root items or nested children)
- *
- * This provider displays a two-level hierarchy:
- * - Level 1: RunTreeItem (dbt command executions like "dbt run +model1")
- * - Level 2: ModelResultTreeItem (individual model/test/seed results)
