This commit adds support for Istio ambient mode (sidecar-less data plane) to all Pulsar components in the Helm chart, following the design from sn-operator/docs/proposals/istio-ambient-mode-design.md. Changes: - Add dataplaneMode field to values.yaml istio section (defaults to empty for backward compatibility) - Update PulsarBroker template to include dataplaneMode in istio config - Update PulsarProxy template to include dataplaneMode in istio config - Add istio section with dataplaneMode to BookKeeperCluster template - Add istio section with dataplaneMode to ZooKeeperCluster template Benefits: - Backward compatible (empty value defaults to sidecar mode via API) - Enables ~70-80% resource savings with ambient mode - Supports migration mode with permissive mTLS - All components (Broker, Proxy, BookKeeper, ZooKeeper) support ambient mode Usage: Set istio.dataplaneMode: "ambient" to enable sidecar-less data plane Set istio.dataplaneMode: "sidecar" or leave empty for traditional sidecar mode 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
