- Deleted `I18N_IMPLEMENTATION_PLAN.md` and `PROJECT_PROGRESS.md` to declutter the repository.
- These documents were finalized, no longer relevant, and superseded by implemented features and external references.
- Introduced `CONTRIBUTING.md` to provide detailed guidelines for contributing, covering coding standards, testing, commit messages, and the pull request process.
- Added a new `README.md` to document the project setup, features, tech stack, testing infrastructure, and deployment instructions.
- Improved accessibility and structure of developer resources for better onboarding and collaboration.
