Fixed
- With two or more Codex panes, one pane's chat could show another pane's conversation. Since
Codex 0.157 every Codex TUI shares one app-server daemon, and that daemon reports each TUI's
thread to herdr as the thread of the pane that started it. That report is now only a fallback:
what the pane shows on screen decides, and a thread another pane shows, is bound to, or was
resumed on is never taken for it.
