I'm looking for a gem which could help to organize command line (CLI) input options and/or arguments and output to end user as well.
Something like in Symfony/Console (PHP).

Commander is quite good. Also, check out the book Build Awesome Command Line Applications in Ruby 2.

I'm usually a backend developer so whenever I need to make website look nice I just apply bootstrap themes to do the job extremely efficiently and well. Is there an equivalent framework with much support and resources that could help my Flutter apps not look so basic?
Why do you need Bootstrap, when you have Materal and Cupertino?

Is there a way to download the new RC so I do not have to use Compass or Ruby? I have looked on Github.
You can download it from the releases section of the project. Please be aware that it requires Breakpoint 2.4.x and will only compile using a compiler that has feature parity with Sass 3.3, which as of right now is only the Sass 3.3.0.rc.x gems (so Ruby is still required at the moment for that gem)

I have some forks in my Rakefile and I want to dive into what each process does and I was wondering if there are any good tutorials out there on debugging a ruby program that has threads with a debugger. I'm looking for something that shows you how to attach to a newly created thread and so forth.
The RubyMine IDE has good process debugging and it's pretty intuitive. I'm going to use that.
Here's a quickstart guide they give you

I read about a gem months ago that implements a simple DSL to make it easy to handle the complex rerouting operations, similar to the .htaccess file in Apache. But I can't remember what it was called, and haven't bookmarked it unfortunately.
Does anyone know what I'm talking about?!
Found it! I believe this was the one.

Is there a Java library/API available to interact with Windows OS, like executing commands on the command prompt and returning the output back to the program?
You can use java.lang.Runtime.exec() to do it, but read this first.
Use the ProcessBuilder, which is available starting from Java 1.5!
It has the nice ability to let you redirect the error stream which makes you only have to cope with one InputStream to read from.
Good article here: Runtime.exec() and the API is here: link text
