Deprecated outdated roadmap files and updated Architect playbook to reflect new ownership and delegation responsibilities. Introduced architecture improvement proposals and added related documents for enhanced collaboration and knowledge sharing.
Implemented a standardized folder structure for domain documentation to improve clarity and maintainability. Migrated existing files to the new structure, updated links in related documentation, and added README files for navigation and guidance.
Enhanced `ping-service` documentation with architectural, implementation, and API details. Added a new journal entry outlining the troubleshooting steps for backend startup issues, including fixes for Dockerfile paths, Gradle build conflicts, and Keycloak pre-build configuration.

Umfangreiches Refactoring der Projektkonfiguration zur klaren Trennung von Build-, Runtime- und Applikations-Logik.
Änderungen im Detail:
- Struktur: Neuorganisation des `config/` Verzeichnisses in logische Bereiche:
- `config/docker`: Reine Infrastruktur-Configs (Postgres, Redis, Nginx, Monitoring).
- `config/quality`: Statische Code-Analyse (Detekt, Lint).
- `config/app`: Gemeinsame Spring-Boot-Konfigurationen.
- Docker Compose:
- Einführung von Profilen (`infra`, `backend`, `ops`, `gui`, `tools`) für gezieltes Starten von Teilbereichen.
- Anpassung aller Volume-Pfade auf die neue Struktur.
- Spring Boot Config:
- Zentralisierung gemeinsamer Einstellungen (Datasource, Redis, JPA) in `config/app/base-application.yml`.
- Parametrisierung der Hosts für nahtlosen Wechsel zwischen Docker und Localhost.
- Bereinigung der service-spezifischen `application.yaml` Dateien (z.B. Ping-Service).
- Cleanup: Entfernen redundanter "Ghost-Files" (`versions.toml`, `central.toml`, `config/.env`), um eine echte Single Source of Truth (SSoT) zu gewährleisten.
