Simple MPSCQueue with explanation

I wanted to learn about **lock-free programming**. To do that, I decided to implement an **MPSC (Multiple Producer, Single Consumer) queue**, but I quickly realized that the entry barrier is very high—at first, I had literally no idea where to start.

I spent several weeks gathering knowledge bit by bit, studying multithreading, atomics, memory ordering, and lock-free algorithms. Eventually, I was able to come up with an algorithm, implement it, and debug it successfully.

I thought it would be valuable to create a detailed walkthrough, written while the experience is still fresh. My goal is that this can be useful:

* For myself in the future, if I need to revisit lock-free queues.
* For friends or anyone just starting with concurrency.
* For anyone interested in understanding the **basics of low-latency, high-performance, lock-free concepts**.

I would have loved to have an article like this while I was learning, so I hope it helps others in the same way.
