[BUG] Open files in VS Code UI don't refresh when the Claude Code plugin edits the files in a Dev Container.

What's Wrong?

When Claude Code is running in a Dev Container from the Claude Code plugin and it makes edits to files, but the file is open in a VS Code editor window, the window is not refreshed. The workaround, closing and opening all edited files, is prohibitive to use. This is a plugin bug because Claude Code when used from CoPilot always refreshes and the proposed changes are always visible.

What Should Happen?

When Claude Code edits a file, even in a dev container, the edits should appear in the editor window.
