Updated module path and significantly extended the StoneError implementation with new functionality, including metadata handling, error wrapping, JSON serialization, and utilities like `IsStoneError`. Enhanced README with detailed examples, usage guidelines, and a thematic introduction.
This commit initializes the project with Go module support and a basic `StoneError` struct. It also introduces .gitignore, SonarQube configuration, and multiple CI/CD workflows for branch, tag, and protected branch scenarios to automate testing, static analysis, and builds.
