FIX: resolve ruff style failures blocking CI

- doc/conf.py line 675: split `return orig_pooch_fetch(...)` string
  literal across multiple lines to stay within the 88-char limit (E501)
- mne/parallel.py: move docstring before the emscripten early-return so
  it is the first statement in the function (required by pydocstyle/ruff)
