CmdSpace 0.0.7

Added

• Drag-to-Applications DMG installer. Releases now ship a .dmg alongside the existing .zip. Opening the disk image shows the CmdSpace app on the left and an Applications folder on the right with a guiding arrow, so first-time installs are the familiar drag-across flow used by most macOS apps. The .zip is retained for Sparkle auto-updates. The DMG is Developer-ID-signed, notarized, and stapled on tagged releases.
