Regression: "Open in VS Code" moved from one-click session action to Changes-panel dropdown

Describe the bug

Previously, "Open in VS Code" was a single, directly-clickable button in the session action bar, right next to "Create PR". Now it requires: opening the Changes panel/tab, clicking a small icon button, then selecting "Visual Studio Code" from an "Open in..." dropdown (which also lists Windows Terminal, PowerShell, Visual Studio 2019/2022, etc.). There's no "customize toolbar" option to pin VS Code back as a direct one-click action.

Affected version

1.0.80 (Windows)

Steps to reproduce

1. Open a project session with uncommitted changes.
2. Look for a way to open the changes in VS Code.
3. Note it's no longer next to "Create PR" — you must open the Changes tab, click the small app-icon button, and choose "Visual Studio Code" from the dropdown each time.

Expected behavior

"Open in VS Code" (or last-used editor) should be a single click accessible from the main session action bar, as it was before, or the dropdown should remember/default to the last-selected app.

Additional context

OS: Windows

Reproduisez le flux Windows 1.0.80 avec une session contenant des modifications non validées, puis suivez la barre d’actions de la session et le contrôle "Open in..." du Changes-panel. La tâche est terminée lorsqu’une action en un clic pour VS Code ou le dernier éditeur utilisé est restaurée, ou lorsque la liste déroulante mémorise la sélection, et que le flux concerné est couvert par un test de régression.
