Introduce Static Code Analysis and Refine Encapsulation in SDK

[thebhumilsoni]

💬 Summary of Changes

This PR enhances the project's code quality and maintainability by introducing a static code analysis plugin, enhancing API encapsulation, and refining our build and testing workflows. The changes are aimed at ensuring high coding standards and improving the encapsulation within our SDK.

• Introduced a static code analysis plugin to lint the project using detekt.
• Addressed and fixed all project lint issues identified by detekt.
• Added pre-push git hook requiring lint checks to pass, preventing commits with potential quality issues being pushed.
• Integrated a lint step into the SDK's build and test workflow, automating code quality checks.
• Updated SDK API access to improve encapsulation--restricting access to internal components.

📝 Items of Note

• Integrating pre-push git hooks alongside our CI workflow's lint step adheres to 'fail-early' strategy, helping to identify and fix linting issues locally before pushing to the repository. This helps with minimises waiting for CI feedback and ensures locally bypassed lint checks are covered by CI, maintaining high standards for code quality.
