feat: Demonstrate newline character usage with println [newline-demo]

🧠 Logic:
- Prints a string using `\n` escape sequence to break into two lines.
- `"Hello\nWorld"` results in:
  Hello
  World

📘 Purpose:
- Demonstrates how newline `\n` works inside `System.out.println()`.
- Useful for learning escape characters in Java string formatting.

✅ Output formatting:
- This is especially relevant for CLI/terminal output, text layout, and competitive programming.
