feat(tui): surface the failure reason on failed downloads

Carry a human-readable reason on DownloadStatus::Failed so it flows through the existing status channel to the TUI. The download Info pane now shows an Error line for a failed download (connect failure, peer disconnect, truncated transfer, peer-reported upload failure, or the underlying transfer error). Failures without a known reason render as before.
