Bump version

* remove support for uninstalling old sunset apps

* Add color legend on app removal screen

* Remove legacy app list generator and custom apps file support
Replaced by GUI config export/import, dynamic RemovalMethod, and
CLI app removal settings saved to LastUsedSettings.json.

* Verify app removal by checking actual installation state instead of trusting winget output

+    .SYNOPSIS
+    Returns a list of installed apps from winget as structured objects.
 
-# Run winget list and return installed apps.
-# Use -NonBlocking to keep the UI responsive (GUI mode) via Invoke-NonBlocking.
+    .DESCRIPTION
+    Runs `winget list` and parses the output into PSCustomObject arrays.
+    Use -NonBlocking to keep the UI responsive in GUI mode; otherwise
+    runs synchronously with an optional timeout.
+
+    .PARAMETER TimeOut
+    Maximum seconds to wait for winget to complete. Default is 10.
+
+    .PARAMETER NonBlocking
+    When set, runs via Invoke-NonBlocking so the GUI thread stays responsive.
+
+    .OUTPUTS
+    PSCustomObject[] with Name and Id properties. Returns $null on
+    failure, or an empty array when winget succeeds but lists no apps.

-# Removes apps specified during function call based on the target scope.
+<#
+    .SYNOPSIS
+    Removes one or more Windows app packages based on the target scope.
+
+    .DESCRIPTION
+    Iterates over the provided list of app identifiers and removes each one.
+    The removal method (winget vs. Appx cmdlets) is determined per-app from
+    Apps.json. Microsoft Edge is deferred to the end of the loop so that all
+    winget attempts run before any force-remove prompt. A scheduled task is
+    only created when the User or Sysprep parameter was passed.
+    After each winget removal, the system is checked to confirm whether the
+    app is still installed before reporting an error.
+
+    .PARAMETER appsList
+    An array of app package identifiers to remove (e.g. 'Microsoft.BingNews').
+
+    .EXAMPLE
+    RemoveApps @('Microsoft.BingNews', 'Microsoft.BingWeather')
