/**
 * E2E tests for the repo-grouped task sidebar layout.
 *
 * Covers:
 *   - Repo group headers: letter avatar, task count, collapsible
 *   - Subtasks (parent_id): nested under parent with arrow indicator
 *   - Unassigned group: tasks with no repo
 *   - Context menu: Rename, Archive, Delete options via right-click
 *   - Active task highlight: selected task has aria/visual selection state
