fix: final homebrew cask style + audit cleanup

- Drop unnecessary verified: stanza (URL host matches homepage host).
- Add blank line between sha256 and url inside on_arm/on_intel
  (rubocop treats them as separate stanza groups).
- Keep no blank line between on_arm and on_intel blocks
  (same outer stanza group).

After re-running the bump workflow, the cask passes both
brew audit --cask and brew style --cask cleanly.
