Included a GitHub release badge to display the latest release version directly in the README. This improves visibility of the project's current state and provides quick access to the release details.
Replaced the broken relative javadoc link with a working absolute URL pointing to the hosted documentation. This ensures easier access to the API reference for users.
Introduce Javadoc-related files (`javadoc.sh`, `options`, and `packages`) for API documentation generation. Update README to improve clarity on usage examples and remove redundant "Example" headings for a cleaner presentation.
