Add CLI and Fibonacci scripts, and implement Rectangle area calculation#129
Conversation
Reviewer's GuideAdds three standalone Ruby scripts: cli.rb introduces a command-line interface for customizable message printing using OptionParser; fibonacci.rb implements an iterative fib function with user input to generate and print a sequence; shapes.rb defines an Area module and a Rectangle class with area calculation and provides a usage example.

**suggestion:** Consider validating input for negative or zero values for 'times'.
Without validation, negative or zero values for '-n'/'--number' may cause the script to fail silently or act unpredictably. Please add a check to ensure 'times' is a positive integer.
</issue_to_address>
### Comment 2

**suggestion:** No input validation for non-integer or negative values.
Validate 'm' to ensure it is a non-negative integer to prevent unexpected behavior.
