/**
 * Transforms a bulletList, orderedList, or taskList into a decisionList.
 *
 * Notes
 * - decisionLists and taskList only support text as children - need to ensure content is converted to text
 *
 * @example
 * Input (nested bulletList):
 * - bulletList
 *   - listItem "1.1"
 *   - listItem "1.2"
 *   - listItem "1.3"
 *
 * Output (flat decisionList):
 * - decisionList
 *   - decisionItem "1"
 *   - decisionItem "1.1"
 *   - decisionItem "2"
 *
 * @param nodes - Array of nodes to transform
 * @param context - Transform context with schema and target node type
 * @returns array of transformed nodes
