SingleSelectableTask

A task that ensures only one item can be selected at a time from a list of ViewData.

This task filters out AppInfoViewData instances from the input list, extracts their SelectableItem objects, and then manages their selection state.

Key behaviors:

• If no items are initially selected, the first item in the list will be selected by default.

• When an item is selected, all other items are automatically deselected.

• Listeners are registered on each SelectableItem to enforce the single-selection rule.

• Previous listeners are disposed of before new ones are registered to prevent memory leaks.

• The task returns the original input list, with the selection states of the SelectableItem objects updated.
