Functionality has been tested, no obvious bugs
Code style follows project conventions
Documentation/comments updated (if applicable): no separate documentation change is needed for this caption button

Brief Description of Changes

When ShowInTaskbar=true, the preview window appears on the taskbar but has no minimize button. Add a caption button next to maximize that sets WindowState.Minimized. Bind its visibility to ShowInTaskbar, so it stays hidden when the option is disabled.

Use the existing caption style and translation helper. Add MW_Minimize in all 29 locale sections for the tooltip and accessibility name.

Closes #2015.

Context: #1789 (comment)

Walkthrough

A minimize button is added to the window caption. When ShowInTaskbar is true, users can click it to minimize the window. The button’s tooltip and UI Automation name use the new MW_Minimize translations, added for 29 languages.

Merge Risk: Low · previous review 9334e

Users with CloseOnLostFocus enabled may lose the minimized preview instead of restoring it from the taskbar. This should be fixed before relying on the new minimize button.

Do not close the preview after an intentional minimize.

When CloseOnLostFocus is enabled, minimizing an unpinned visible window can trigger Deactivated. The queued callback then calls Close() because it checks only IsVisible && !Pinned. Exclude WindowState.Minimized so the taskbar window remains restorable.

Proposed fix

- if (IsVisible && !Pinned) + if (IsVisible && WindowState != WindowState.Minimized && !Pinned) Close();
