Installer & Update Notifier/Automatic Updates

Please consider releasing a installer version which will also have a setting which can check for updates on Privatezilla or updating Privatezilla automatically and notify the user when an update has been made and privacy settings should be reviewed.

The issue names no files, tests, or entry points. First map how Privatezilla is packaged as a Windows application and how its settings and notifications are handled, then clarify the expected installer, update-checking, automatic-update, and privacy-review flows. Done requires an agreed design and acceptance criteria for those behaviors.
