  -- those nested adds only register the paths on the NEXT event loop tick
  -- — so a synchronous follow-up `require('persistent-breakpoints')`
  -- crashes with "module not found". `vim.schedule` lets the pack module
  -- finalize before we retry. `_setup_called` still gets set on the retry,
  -- so plugin/turbo-debug.lua's own deferred auto-setup correctly skips.
