Changed-file rows are easier to scan when previewable files are grouped before source-only files, and the file open-with menu should only expose useful preview, editor, and reveal actions. Output target cards also no longer need a separate copy control now that open/open-with are the primary actions.
Constraint: Keep the existing open-with API and menu components shared across changed files, workspace context menus, and output target cards.
Rejected: Keep system-default open for files | it duplicated less predictable platform behavior and added a low-value final menu item.
Confidence: high
Scope-risk: narrow
Directive: File open-with menus should stay ordered by immediate preview/open usefulness before editor and reveal actions.

A turn can touch many files; an open-with affordance on every row is noise.
Restrict the per-file 打开方式 pill to rendered-previewable types via a new
isPreviewableChangedFile() predicate. Source rows keep their inline diff toggle.

Each file row now shows a material-symbol document-type icon, bold filename,
and a type subtitle (e.g. 文档·MD / 代码·TS) alongside a labeled 「打开方式 ⌄」
pill replacing the old open_in_new icon button; diff-expand is preserved.
