/**
 * Gets the end-of-line sequence from a string.
 *
 * This function analyzes the given string to determine the most frequent end-of-line (EOL)
 * sequence. It counts the occurrences of carriage return line feed (`\r\n`) and
 * line feed (`\n`).
 *
 * @param content The string to process.
 * @returns The most frequent EOL sequence. If `\r\n` is more frequent, it returns `\r\n`.
 * Otherwise (including ties), it returns `\n`. If no newlines are found, it falls back
 * to the operating system's default EOL sequence.
