/**

 * Parses a full name string using a custom delimiter and returns either the first or last part.
 *
 * - If the delimiter is found, it splits and returns based on order (e.g., "Last, First").
 * - If the delimiter is not found, it splits by whitespace and uses fallback logic:
 *    - If the selected word is 3 characters or less, it attempts to return 2 words
 *      to avoid edge cases like "Mr.", "Sr.", "I", "II", etc.
 *
 * @param name - The full name string (e.g., "LastName, FirstName" or "John Smith").
 * @param delimiter - The delimiter to split on (e.g., ",", "|", "/").
 * @param part - "First" or "Last" to specify which part to return.
 * @param onError - 'Empty' | 'Original' = 'Original' return either empty string or the original
 * @returns The parsed first or last name as a string.
 *
 * @example
 * parseName("Doe, John", ",", "First") // Returns "John"
 * parseName("Doe, John", ",", "Last")  // Returns "Doe"
 *
 * @example
 * parseName("John Smith", ",", "First") // Returns "John"
 * parseName("John Smith", ",", "Last")  // Returns "Smith"
 *
 * @example
 * parseName("Mr. John Smith", ",", "First") // Returns "John"
 * parseName("Sr. Alex", ",", "Last")        // Returns "Alex"
 *
 * @example
 * parseName("I Smith", ",", "First") // Returns "I Smith" (because "I" is <= 3 characters)
 * parseName("J Smith", ",", "Last")  // Returns "J Smith"
 *
 * @example
 * parseName('Doe, John');            // "Doe"   (default 'Last', default delimiter)
 * parseName('John Smith', 'First');  // "John"  (uses default delimiter, even though it's not present)
 * parseName('John | Smith', 'Last', '|'); // "Smith"
