Enhance macOS deployment with Sparkle integration and update build scripts

This commit refines the CMake configuration for macOS by finding the Sparkle framework early in the build process, allowing it to be bundled with the application. The Dmg.cmake script is updated to handle Sparkle's framework paths and ensure proper deployment. Additionally, the build_sign_notarize.sh script is improved to sign Sparkle's helper executables correctly and includes enhanced notarization feedback. The Brewfile and install_brew_deps.sh are also updated to include the new macdeploycheck dependency for better deployment checks.
