macOS app: file context menu 'Open in → Finder' does nothing (silent, no error)

What happened

In the Claude Code macOS desktop app, right-clicking a file link in the conversation transcript shows a context menu with Copy path, Copy relative path, Copy filename, and Open in → Finder.

The Copy actions all work. Open in → Finder does nothing: no Finder window opens, no file is revealed, and no error is shown anywhere in the UI. It fails silently.

Expected

Selecting Open in → Finder should reveal/select the file in a Finder window (equivalent to open -R <path>).

Ideally the Open in submenu would also offer opening the file in other applications (e.g. the default app for the filetype, or a chosen editor), not just Finder.

Steps to reproduce

1. In a session, have the assistant reference a file as a clickable link in its response.
2. Right-click the file link to bring up the context menu.
3. Hover Open in, then click Finder.
4. Observe: nothing happens. Finder does not come forward and the file is not revealed.

Notes

• Copy path / Copy relative path / Copy filename from the same menu work correctly, so the menu wiring and path resolution are fine; the failure is specifically in the shell-out to open Finder.
• The failure is silent (no toast, no error dialog, no console-visible error from the user's side), which suggests the underlying error is being swallowed rather than surfaced.

Environment

• Claude Code macOS desktop app
• macOS: Darwin 25.3.0 (arm64)
