[Feature request] Notification when Codex web finishes a task

Dear development team,

You’ve made Codex (speaking of web version) feel more user-friendly. I need a “task complete” notification. When I run different jobs in parallel, I often miss a finished task for 15+ minutes; it usually still needs more passes. That delay between iterations slows me down. I want to focus on other work instead of polling or watching Codex run.

Request: Opt-in completion alerts (desktop push, email or in-app). Any notification is better than none. What would block shipping this?
