fix(tui/jump-back): fully reset UI state after fork to prevent stalls\n\nWhen jump-back forks a new conversation, create the new ChatWidget, run initial animations, clear transient Esc state, stop any commit animations, and force a clean repaint.\n\nAddresses a hang where the app appeared unresponsive after sending a message post jump‑back.\n\nCloses #15
