feat: Improve release workflow and update README

This commit introduces two main improvements in a single, clean commit:

1.  **Release Workflow:** The GitHub Actions workflow for creating
    releases has been updated to be more robust and user-friendly.
    - It now automatically generates a changelog based on the commit
      history since the last tag.
    - The release description is now managed via a standard, multi-line
      bash string, which is easy to edit and avoids YAML parsing issues.

2.  **README Banners:** The shield.io banner icons in `README.md`
    are now linkable, pointing to their respective pages on GitHub
    (e.g., Releases, Issues).
