This pull request adds support for managing Adobe DNG Converter on
macOS. The main changes include introducing metadata and
installation/uninstallation scripts for this application, updating the
app registry, and improving version detection logic to handle Adobe’s
unique versioning format.
**Support for Adobe DNG Converter:**
* Added a new input definition for Adobe DNG Converter in
`homebrew/adobe-dng-converter.json`, specifying its identifiers,
installer format, and default category.
* Generated an output manifest in
`outputs/adobe-dng-converter/darwin.json` with version info, download
URL, SHA256, and detailed install/uninstall scripts for managing the app
lifecycle.
* Registered Adobe DNG Converter in the main `apps.json` registry,
including a description, unique identifier, and platform.
**Improvements to version detection:**
* Updated the `appExists` function in `darwin.go` to correctly detect
Adobe DNG Converter even when the installed version string includes a
build number in parentheses, improving reliability of version checks.
