 * Direct function wrapper for adding a new task with error handling.

 * @param {string} [args.title] - Task title (for manual task creation)
 * @param {string} [args.description] - Task description (for manual task creation)
 * @param {string} [args.details] - Implementation details (for manual task creation)
 * @param {string} [args.testStrategy] - Test strategy (for manual task creation)
 * @param {string} [args.dependencies] - Comma-separated list of task IDs this task depends on
 * @param {string} [args.priority='medium'] - Task priority (high, medium, low)
 * @param {string} [args.tasksJsonPath] - Path to the tasks.json file (resolved by tool)
 * @param {boolean} [args.research=false] - Whether to use research capabilities for task creation
 * @param {string} [args.projectRoot] - Project root path
 * @param {Object} log - Logger object
 * @param {Object} context - Additional context (session)
 * @returns {Promise<Object>} - Result object { success: boolean, data?: any, error?: { code: string, message: string } }
