+ * Removes code fence markers (```) surrounding an artifact element while preserving the artifact content.
+ * This is necessary because artifacts should not be wrapped in code blocks when rendered for rendering action list.
+ *
+ * @param content - The markdown content to process
+ * @returns The processed content with code fence markers removed around artifacts
+ *
+ * @example
+ * // Removes code fences around artifact
+ * const input = "```xml\n<div class='__boltArtifact__'></div>\n```";
+ * stripCodeFenceFromArtifact(input);
+ * // Returns: "\n<div class='__boltArtifact__'></div>\n"
+ *
+ * @remarks
+ * - Only removes code fences that directly wrap an artifact (marked with __boltArtifact__ class)
+ * - Handles code fences with optional language specifications (e.g. ```xml, ```typescript)
+ * - Preserves original content if no artifact is found
+ * - Safely handles edge cases like empty input or artifacts at start/end of content
