/**
 * Reset all user data while keeping auth credentials.
 *
 * Deletes:
 * - DB: user_settings, user_state, user_integrations, dock_configs,
 *        chat_sessions (cascades chat_messages), chat_groups,
 *        dashboards, screens, projects,
 *        task_logs, queue_jobs, terminal_containers
 * - Filesystem: entire $DATA_PATH/<email>/ directory
 *        (home, settings, state, dashboards, chat_sessions, emails.db,
 *         Gmail, skills, tools, tasks, processes, extensions, logs, cache, etc.)
 * - Queue job files: $DATA_PATH/queue/jobs/*.json owned by user
 * - Terminal containers map: removes user entry from terminal-containers.json
 *
 * Preserves:
 * - users table row (account, password, role, status)
 * - passkeys table rows
 * - passkey_challenges, token_blacklist
 *
 * Usage: bun run scripts/reset-user-data.ts <email>
 *        bun run scripts/reset-user-data.ts <email> --yes  (skip confirmation)
