docs(readme): add status badges above the title

Seven badges covering build status, CodeQL scanning, license, latest
release, Dalamud API level, .NET version and FFXIV expansion. Quick
visual indicator that the plugin is healthy and which tooling
generation it targets, plus shortcut links to the workflow runs and
security findings.

 **Version 0.5.1** — DSGVO-bewusste Erweiterung von [Chat 2](https://github.com/Infiziert90/ChatTwo) für FINAL FANTASY XIV / Dalamud.
 
 Hellion Chat baut auf Chat 2 auf und ergänzt es um Datenschutz- und Daten-Handling-Kontrollen, die mit den Datenschutz-Regeln in der EU, den USA und Japan im Einklang sind. Alle Chat-2-Funktionen, Befehle und Tastenkürzel funktionieren unverändert. Eigenständiger Plugin-Slot, eigene Konfiguration, eigene Datenbank.
