## Description This PR fixes an issue where Twilio WhatsApp messages were losing newlines and markdown formatting. The problem had two root causes: 1. Text-based renderers (WhatsApp, Instagram, SMS) were converting newlines to spaces when processing plain text without markdown list markers 2. Twilio WhatsApp channels were incorrectly using the plain text renderer instead of the WhatsApp renderer, stripping all markdown formatting The fix updates the markdown rendering system to: - Preserve newlines by overriding the `softbreak` method in WhatsApp, Instagram, and PlainText renderers - Detect Twilio WhatsApp channels (via the `medium` field) and route them to use the WhatsApp renderer - Maintain backward compatibility with existing code ## Type of change - [x] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality not to work as expected) - [ ] This change requires a documentation update ## How Has This Been Tested? Added comprehensive test coverage: - 3 new tests for newline preservation in WhatsApp, Instagram, and SMS channels - 4 new tests for Twilio WhatsApp specific behavior (medium detection, formatting preservation, backward compatibility) - All 53 tests passing (up from 50) Manual testing verified: - Twilio WhatsApp messages with plain text preserve newlines - Twilio WhatsApp messages with markdown preserve formatting (bold, italic, links) - Regular WhatsApp, Instagram, and SMS channels continue to work correctly - Backward compatibility maintained when channel parameter is not provided ## Checklist: - [x] My code follows the style guidelines of this project - [x] I have performed a self-review of my code - [x] I have commented on my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [x] Any dependent changes have been merged and published in downstream modules
