Prevent removal of `pin to taskbar` on Windows

Editor assessment

An excellent subject for a user-facing installer bug: 'prevent removal of `pin to taskbar` on Windows' names the exact user-visible symptom and the platform, backticks the affected feature, and stays compact. The bundler scope is correct since the defect lives in what the installer writes and removes, and the fix type matches. Nothing violates the spec — imperative mood, lowercase start, no trailing period, sensible length. The improvement opportunity is a body explaining the mechanism (a WiX component condition? an upgrade removing the shortcut flag?) so future maintainers understand what the installer was doing wrong. For changelog purposes the subject already communicates the fix to end users, which is the main goal.
