Subject: [PATCH] feat(windows): support displaying and opening .lnk shortcut
 files

Show .lnk shortcut files in the sidebar only when they point to file types natively supported by MarkText (e.g., .md, .txt). When such a shortcut is clicked, its target file is opened directly. Shortcuts pointing to unsupported file types are filtered out and do not appear in the sidebar.
