Installation and dependency changes

The foundational deployment setup for companion databases has been updated:

  • Helm Repository Consolidation: The installation instructions now require explicitly registering both the official Percona and Valkey Helm repositories before launching system charts.

  • PostgreSQL Password Management: The PostgreSQL password variables inside the standard values.yaml chart are now commented out by default to maximize environment security. Upgrading environments must now pre-create a Kubernetes Secret or explicitly declare their existing credentials to prevent broken database connections during the cutover phase.
