fix(profile): add timeout to clientedit, guard clearAvatar with generation

- Wrap clientedit (description) with 5s timeout to prevent blocking
  channel description and now-playing updates if the command hangs
- Check generation counter in clearAvatar to avoid clearing a newer
  song's avatar when stop→play happens in quick succession
