// Handle terminal death signals to prevent orphaned processes.
// When a controlling terminal is destroyed (SSH disconnect, tmux pane close, etc.),
// the kernel sends SIGHUP. Without this handler, the process continues running
// indefinitely because the TUI event loop blocks on stdin that will never arrive,
// preventing the `process.exit()` in the finally block from ever executing.
// This was observed to leak ~4.7 GB per orphaned instance.
