feat: Demonstrate tab character usage in println [tab-char-demo]

🔑 Key: tab-char-demo
🧠 Logic:
- Prints a string using `\t` escape character to insert a horizontal tab.
- `"Name:\tJohn"` aligns output in a spaced format, like:
  Name:    John

📘 Purpose:
- Shows how `\t` creates uniform spacing between content.
- Useful in console UIs, tabular data display, and formatting structured output.

💡 Tip:
- Multiple `\t` can be chained for more spacing.
