Enum
FileMode
Controls whether FileSystemService normalizes line endings when
reading or writing files.
The FileMode enum is passed to FileSystemService:ReadFile() and
FileSystemService:WriteFile() to control line-ending handling.
FileMode.Text normalizes \r\n sequences to \n on both read and
write, ensuring consistent cross-platform behavior when working with text
content. FileMode.Binary performs no transformation, preserving every
byte exactly as stored on disk.
