Change

README badges for CI Tests and JUnit 6 were not rendering reliably on GitHub due to badge URL parameter issues. This updates only those badge image URLs to valid Shields parameters while preserving existing labels, links, style, and README content.

• Badge URL fixes
  • CI Tests badge keeps the ci.yml workflow target on master and uses a valid logo slug.
  • JUnit 6 badge keeps the JUnit docs link and uses a valid JUnit logo slug.
• Scope
  • README-only, surgical change (no gameplay/build/test logic touched).

[![CI Tests](https://img.shields.io/github/actions/workflow/status/cihat-kose/emberbound/ci.yml?branch=master&style=for-the-badge&label=CI%20Tests&logo=githubactions&logoColor=white)](https://github.com/cihat-kose/emberbound/actions/workflows/ci.yml)
[![JUnit 6](https://img.shields.io/badge/JUnit%206-25A162?style=for-the-badge&logo=junit5&logoColor=white)](https://docs.junit.org/6.1.3/overview.html)

Validation

• mvnw verify passes (use mvnw.cmd on Windows).
• Relevant gameplay or persistence regressions are covered.
• Gameplay rules and documentation agree.

Include a short transcript when changing the player experience.
