This PR adds version and status badges to both README.md and README.es.md files using shields.io, improving visibility for contributors and users.

Changes Made

Added badges:

• Version Badge: Displays the current release version from GitHub releases
• Build Status Badge: Shows the status of the GitHub Actions workflow for Python API tests

Implementation details:

• Version badge uses https://img.shields.io/github/v/release/drneox/tzu and links to the GitHub releases page
• Build status badge uses https://img.shields.io/github/actions/workflow/status/drneox/tzu/python-app-test.yml and links to the GitHub Actions workflow
• Both badges are positioned at the top of the README files for maximum visibility
• Spanish translations are provided for the badges in README.es.md
