fix(proofing): stop flagging bare URLs as misspelled on macOS

NSSpellChecker's implicit URL handling is unreliable for URLs alone on a
line (a bookmark list), flagging the whole URL as one misspelling. Request
the link checking type alongside spelling so the data detector claims URL
ranges, then keep only spelling results. Real misspellings are unaffected.
