/**
 * A single component for both shapes of tree data:
 * - Eager: every node's full subtree is already in `data` via `children`.
 *   No `loadChildren` needed - toggling a node only ever flips its
 *   expanded/collapsed state.
 * - Lazy: `data` only has to contain what you already know; pass
 *   `loadChildren` and a node whose `children` is undefined gets fetched
 *   the first time it's expanded (see TreeNode's docs on `hasChildren` for
 *   how a not-yet-fetched node still shows a toggle).
 *
 * Expand/collapse state follows the same model as the Sidebar: a single
 * `Set<string>` of expanded ids is the source of truth (see
 * useTreeExpansion), and it can be left uncontrolled or owned by the
 * caller via `expandedIds`/`onExpandedIdsChange`.
