 -- Note: supermaven's built-in `condition` option is one-way — its BufEnter
 -- listener gates the restart branch on `vim.g.SUPERMAVEN_DISABLED`, which
 -- `api.stop()` itself sets, so once auto-stopped it never comes back. This
 -- autocmd owns both directions instead. `vim.g.supermaven_leetcode_stopped`
 -- distinguishes our auto-stop from a manual :SupermavenStop, which stays off.
