[app][Windows] Realtime Voice started from a project creates a projectless task in a temporary workspace

Summary

On Codex Desktop for Windows, starting a realtime Voice chat while working in a saved local project creates a new projectless task in a temporary Documents\Codex\...\realtime-voice-chat workspace instead of preserving the active project's association and working directory.

The Voice session itself starts and works. The failure is the thread/project association.

Environment

• Codex Desktop package: OpenAI.Codex 26.721.4979.0 (Microsoft Store)
• Platform: Windows 10, x64, build 19045

Steps to reproduce

1. Open Codex Desktop.
2. Select a saved local Git project.
3. Open a task in that project.
4. Start a new real-time Voice chat.
5. Speak normally and allow the Voice task to be created.
6. Inspect the created task's project association and working directory.

Expected behavior

The realtime Voice task should inherit the active saved project's ID and working directory, or any task delegated by Voice should be explicitly associated with that project.

Project-level context such as AGENTS.md, repository files, and the active working directory should remain available.

Actual behavior

Each Voice task is created with no project association and a temporary working directory such as:

C:\Users\<user>\Documents\Codex\2026-07-26\realtime-voice-chat
C:\Users\<user>\Documents\Codex\2026-07-26\realtime-voice-chat-2

Local app inspection shows:

• the intended local project is registered with a non-null project ID and its real repository path;
• each affected Voice thread has projectId = null;
• each affected Voice thread uses a generated realtime-voice-chat directory instead of the repository;
• the behavior occurred in three consecutive Voice sessions.

As a result, the Voice task does not load the repository's AGENTS.md or project files.
