Feature request: Headless Codex computer-use (server-side UI automation)

Expose Codex computer-use as a headless, server-side capability that can be invoked programmatically. Today, computer-use is tied to a user desktop/session; the request is the ability to spawn an isolated agent task that can navigate and operate a UI (browser or app) purely from an API call, returning structured results and execution logs. Example: employee onboarding across multiple third-party systems that have no APIs. A backend service issues a single request (“create user, assign roles, enroll in systems”), and the agent completes each step by interacting with the UIs directly in a headless environment, returning success/failure per system.
