codex - 💡(How to fix) Fix Recent projects sidebar order does not update when switching active workspace

What happened

In the Codex Windows desktop app, the sidebar "Recent projects" grouping does not appear to reorder projects by recent activity after switching/opening a project.

Environment

• OS: Windows
• Codex desktop app package: Microsoft Store / WindowsApps
• Appx package observed locally: OpenAI.Codex_26.506.2212.0_x64__2p2nqsd0c76g0
• Repository target: openai/codex

Evidence from local inspection

The persisted global state has:

• sidebar-organize-mode-v1: recent
• active-workspace-roots: changes when switching the active project
• project-order: remains in its previous order unless a separate add/remove/drop path updates it

A read-only inspection of the packaged app indicates:

• The project grouping/sorting code orders sidebar project groups from persisted PROJECT_ORDER / project-order.
• The main-process handler for electron-set-active-workspace-root updates ACTIVE_WORKSPACE_ROOTS and WORKSPACE_ROOT_OPTIONS, but does not update PROJECT_ORDER.
• Some other paths do update PROJECT_ORDER, for example adding remote projects or certain workspace-root option flows, so the "recent project" order can become stale depending on how the user switches projects.

Expected behavior

When "Recent projects" is selected, switching/opening a local project should move that project to the top of the recent project list, or the project list should otherwise be derived from actual recent project activity.

Actual behavior

The active workspace changes, but the project list can remain ordered by stale project-order, so "Recent projects" appears not to work.

Possible fix

When handling electron-set-active-workspace-root, also update PROJECT_ORDER using the selected root, roughly:

projectOrder = [root, ...existingProjectOrder.filter((entry) => entry !== root)]

and notify any state listeners needed for the sidebar to refresh.
