Changes made for Pathfinder V5 PC's.

Split into two methods: DetectParameterStoreChanges (reads current vs incoming, returns diffs) and WriteParameterStoreOverrides (writes to install override file) Order in PerformInstall: Detect changes before file copy, write overrides after file copy This way the zip can't overwrite our install override, and the new base + new DLL (with the ToDictionary fix) will be on disk when the app restarts

Fixed — needs .Changes.Count since ParameterStoreChangeSet wraps the list. Try rebuilding.
