feat: add Icon Composer

Important: Do not tick a checkbox if you haven’t performed its action. Honesty is indispensable for a smooth review process.

In the following questions <cask> is the token of the cask you're submitting.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online <cask> is error-free.
• brew style --fix <cask> reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new <cask> worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask> worked successfully.
• brew uninstall --cask <cask> worked successfully.

Unsure if this counts as beta software and should therefore not be included here. Also not sure I caught everything for the zap stanza.

Here's a working livecheck

  livecheck do
    url :url
    strategy :extract_plist do |items|
      items["com.apple.IconComposer"]&.short_version
    end
  end

The audit failure here is a "false positive" - Apple has a special case for their own software that doesn't require the same codesigning steps as any others.

Yeah, I figured it was either that or something to do with this being in beta and perhaps only working on macOS 26 (haven't tested on older macOS versions).
