/**
 * MessageRenderer - Renders conversational messages with copy-paste friendly formatting
 *
 * This utility provides consistent rendering for all message types in the CLI conversation
 * interface. Uses color and emoji for visual distinction without boxes that break copy-paste.
 *
 * Design principles:
 * - No boxes in conversation (color + emoji only)
 * - Horizontal separators only (━) - don't interfere with copy
 * - Leverages existing 13-theme system
 * - Preserves copyability of all content
