[Feature] add break flow statement

[pabloosabaterr]

Description

Add support for the break statement from end to end.
break transfers control to the end of the nearest enclosing loop. It can only be used inside loops; using it elsewhere should produce an error. (Switch statements are not yet supported.)

Example

while (condition) {
    if (condition) {
        break;
    }
}

Future Considerations

• Extend support to switch statements in future updates.

Benefits

• Enhances language expressiveness.
• Provides better flow control in loops.
