Some LLM providers output literal \n characters (backslash-n) instead of actual newlines. This causes WhatsApp to display the escape sequences as text rather than rendering line breaks. Add normalizeOutboundTextNewlines() to convert literal \n, \r\n, and \r escape sequences to actual newlines before sending messages via the WhatsApp adapter.
