This commit modifies the default state of the "Automatically search for album cover" and "Automatically search for song lyrics" options to false in the UI and corresponding settings logic. Additionally, it updates the macOS Info.plist to disable automatic update checks by default.
This commit updates the Info.plist.in file to use configurable placeholders for the Sparkle feed URL and public key, allowing downstream builders to customize these values. The CMakeLists.txt file is modified to define default values for these placeholders, enhancing flexibility for third-party builds while preserving upstream behavior.
