/**
 * FileTree — collapsible tree renderer over `FileItem` rows.
 *
 * Lightweight tree over the `FileItem` primitive. Directories render a
 * chevron that toggles expansion; files act as leaves. Supports either
 * uncontrolled expansion (internal state) or controlled via `expandedIds`
 * + `onToggle` (useful for lazy-loading children).
 *
 * Keyboard: rows are reachable via Tab (inherited from `FileItem`). Enter/
 * Space on a file fires `onSelect`; Enter/Space on a dir toggles expansion.
 * ArrowRight expands a dir, ArrowLeft collapses it.
