/**
 * file-tree-node.tsx exports the FileTreeNodeComponent React component.
 * It contains two module-private helpers (formatFileSize and getIconComponent)
 * that are pure functions but cannot be imported for direct testing.
 *
 * We verify the module shape so downstream consumers break fast
 * if the export contract changes.
 *
 * Note: FileTreeNodeComponent is wrapped with React.memo, so typeof returns 'object'
 * instead of 'function'. We check for both to handle the memo wrapper.
