feat: Demonstrate control flow variations using while, do-while, infinite loop, and if-else

🧠 Logic:
- Example 1 (commented): `while` loop that never executes since initial condition `i < 100` is false.
- Example 2 (commented): `do-while` loop that executes once even though `i < 100` is false initially.
- Example 3 (commented): `while(true)` loop using `byte` type which overflows after 127, causing infinite printing.
- Example 4 (active): `if(true)` block runs unconditionally, prints current `i`, increments it, and skips the `else`.
