Given a string and a maximum length, truncate the string to the specified length and append "..." if the original string was longer. If the string is already shorter than or equal to the max length, return it unchanged. If maxLength is less than 3, return the first maxLength characters without ellipsis.

Examples:

Input: text = "Hello World", maxLength = 8 Output: "Hello..." Explanation: The string exceeds 8 characters, so truncate to 5 characters and add "..." Input: text = "Hi", maxLength = 10 Output: "Hi" Explanation: The string is already shorter than the max length, return as-is Input: text = "Test", maxLength = 2 Output: "Te" Explanation: maxLength is less than 3, return first 2 characters without ellipsis
