* fix: repair popup install binding, dialog titles, presets switch, radio groups, JSON, tests
- Invoke-WPFInstall: add param block so the right-click app popup binds
-PackagesToInstall. It previously dropped the argument into $args and
installed the whole selected list instead of the clicked app (or warned
that nothing was selected).
- Replace undefined $AppTitle with "WinUtil" in Install/UnInstall warning
boxes, matching the XAML window title and sibling dialogs.
- tweaks.json: remove stray nested "link" inside the WPFToggleScrollbars
registry entry (dead property; registry entries expose only the six
consumed fields).
- Invoke-WPFPresets: fix dead switch cases to the wildcard-pattern
convention so selectedFeatures/selectedToggles clear correctly.
- Invoke-WPFUIElements: store the group StackPanel in radioButtonGroups so
grouped radio buttons share one container (else branch was unreachable).
- sanity.Tests.ps1: pass the Windows PowerShell parser script via
-EncodedCommand; -Command string marshaling corrupted backticks/quotes and
produced false parse failures.
- install-workflow.Tests.ps1: remove the AppTitle workaround and update
title assertions to "WinUtil"; drop orphaned cleanup lines.
- Add CHANGES.md with technical and plain-language explanations.
Verified: each bug reproduced against HEAD, fixes demonstrated to change
behavior, full Pester suite 471/471.
* Delete
* test: cover the explicit popup install parameter path
Add a regression test invoking Invoke-WPFInstall -PackagesToInstall with a
package different from the default sync.selectedApps selection and assert
the runspace receives the explicit object, mirroring the Initialize-WPFUI
popup call shape. Existing default-path coverage is unchanged.
