Expose safe project and thread ordering APIs for Codex Desktop

What variant of Codex are you using?

App / Codex Desktop

What feature would you like to see?

Codex Desktop supports drag-and-drop organization, but automating it through the UI is unsafe because dropping a thread onto a project changes its project membership instead of merely changing its visual order.

Please expose supported App Server APIs for:

• reading the persisted project and thread display order;
• assigning an explicit order or moving an item before/after another item;
• sorting projects and threads by recent activity;
• distinguishing reorder operations from moving a thread between projects;
• applying an atomic batch reorder;
• returning the resulting order for verification;
• preserving thread-to-project membership during reorder;
• restoring a previous order after failure.

Use case

Users with many long-running projects need external local organizers that can rank projects and threads by activity without editing internal files or using fragile mouse automation.

A supported ordering API would also make accessibility tooling and local workflow automation substantially safer. The key requirement is that a visual reorder must never be confused with changing a thread's project membership.

The issue names no files or tests; begin by mapping the App Server endpoints and data structures for projects, threads, membership, and persisted display order. Review how current drag-and-drop behavior distinguishes reordering from project moves, then identify tests for atomic batches, returned order, membership preservation, and rollback.
