Add support for Logi Tune: include a Homebrew input manifest and
install/uninstall scripts, add a transformer to override the installer
URL to Logitech's enterprise PKG (and set SHA256 to "no_check"), and
register the app in outputs. Also add darwin output refs with version,
installer URL and embedded script refs, update apps.json to list Logi
Tune, and add a frontend icon component + PNG asset and icon map entry.
The PKG override is used because the Homebrew DMG contains a GUI-only
installer without a silent mode; version is still sourced from Homebrew.
