[ADD] - Basic Condition If / Then / Else

Hey,

Control Flow is great but if result is false the flow stop to work.

Is it possible to add the feature If / then /else

exemple:

if [condition]
then [command or call]
else [command or call]

Regards

Start by reviewing the existing Control Flow behavior and how workflow conditions and commands are represented. Define the semantics for true and false results, including how the then and else branches execute, and consider how completion should be verified with focused workflow tests.
