- Strip leading 'v' from VERSION for flexible invocation - Add robust checksum download and verification using sha256sum or shasum - Handle missing checksum tools or entries gracefully with warnings - Update asset naming to include 'v' prefix consistently - Improve platform detection formatting and add trap for temp dir cleanup - Minor echo message updates for better user feedback
