What is new in Purge 1.9.0

## Release highlights

- **Restart to Update**: A new switch in Settings > Updates, "Download and install updates automatically", downloads new versions in the background and installs them the next time Purge quits. Once an update is ready, Check for Updates in the Purge menu, the menu bar menu and the About tab becomes Restart to Update, so you can install it straight away. It's off by default, so nothing changes unless you turn it on.
- **Remove unused simulator runtimes**: Dev Tools has a new Simulator Runtimes section. Each runtime is a copy of iOS, watchOS, tvOS or visionOS that Xcode keeps after downloading it, usually about 8 GB. A runtime is Safe when no simulator uses it, Xcode doesn't build new simulators on it, and it hasn't been used in 30 days. Removing one goes through Apple's own `simctl`, needs no password, and works even after Xcode is deleted. Runtimes are never part of a one-click or scheduled clean, because the only way back is downloading them again.
- **Uninstall with Purge from Finder and the Dock**: Drop an app on Purge's Dock icon, or right-click it in Finder and choose Uninstall with Purge, and the App Uninstaller opens with that app and its leftovers ready to review. Nothing moves until you click Move to Trash. macOS turns new Finder items off by default, so there's a switch for it in Settings > Finder.
