Refactor Project Structure for Improved Readability and Modularity

[TheMhv]

The current project structure can be simplified and made more modular to better support library use cases and improve overall readability. I propose a refactor with the following changes:

Proposed Changes

• Block Breakers ✅

  • Move all functions from src/breakers/block/* → src/block/breakers/* ✅

• Transaction Breakers ✅

  • Move all functions from src/breakers/transaction/* → src/transaction/breakers/* ✅

• API Module

  • Remove the monolithic src/api.rs
  • Split functionalities into separate files (and possibly subfolders as needed)

• CLI Structure

  • Create a new folder: src/cli/
  • Move and split src/cli.rs into multiple files inside src/cli/

• Test Modules

  • Create a new folder: src/test/
  • Move and organize all test-related code into this folder

• Blockchain Features

  • Create a new folder: src/blockchain/ for blockchain-specific logic and functionality

---

Goal:
This refactor aims to:

• Improve project clarity and navigation
• Facilitate future maintenance and scaling
• Make the codebase friendlier for both library consumers and contributors
