/**
 * Transforms a decisionList into a bulletList, orderedList, or taskList.
 * Decision items are converted to the appropriate list item type.
 *
 * @example
 * Input (decisionList):
 * - decisionList
 *   - decisionItem "Task 1"
 *   - decisionItem "Task 2"
 *
 * Output (bulletList):
 * - bulletList
 *   - listItem
 *     - paragraph "Task 1"
 *   - listItem
 *     - paragraph "Task 2"
 *
 * Output (taskList):
 * - taskList
 *   - taskItem
 *     - paragraph "Task 1"
 *   - taskItem
 *     - paragraph "Task 2"
 *
 * @param nodes - Array of nodes to transform
 * @param context - Transform context with schema and target node type
 * @returns array of transformed nodes
