Codex App: add Copy file path / folder path / relative path to file card Open menu

Proposal

Add path-copy actions to the Codex Desktop App file/artifact card Open dropdown.

Suggested actions:

• Copy file path
• Copy folder path
• Copy relative path from project/workspace root

Why

When Codex generates or edits files, users often need to paste exact paths back into Codex, Terminal, Finder, scripts, GitHub issues, or external tools.

Currently the workaround on macOS is:

1. Click Open in folder
2. Select the file in Finder
3. Press Option + Command + C

This works, but it is slow and interrupts the workflow.

Suggested UI

In the existing file card Open dropdown:

• Preview
• Open with app
• Open in folder
• Copy file path
• Copy folder path
• Copy relative path

Scope

This request is for Codex Desktop App file/artifact cards.

It is not about the CLI /copy command or copying chat text.
