Fix terminal restore for hidden TUI output

[parsakhaz]

Summary

• keep normal raw terminal scrollback as the primary history path
• trim raw scrollback on safer ANSI-aware boundaries
• separate alternate-screen/TUI redraw output so Codex repaint traffic does not evict or corrupt shell history
• avoid reset-and-raw-replay refresh while a live TUI is active; resize/refresh the live PTY instead

Testing

• pnpm typecheck
• pnpm lint
