fix(conversation-assistant): version generation and settings button

- Add ./generate-version.sh call in install.sh before swift build
  to ensure AppVersion.swift is regenerated with latest VERSION.json
- Fix openSettings() selector syntax: remove extra parentheses from
  Selector(("...")) and add fallback for macOS 12 and earlier
- Remove test comment
