Breaking Changes

- informer_enabled flag removed, making informer-backed cache the only Kubernetes read path
New Features
- Fast Sandbox integration with Firecracker microVMs and FastPath fleets backend
- Opt-in PostgreSQL snapshot store with multi-process HA coordination
- Stable, scoped diagnostics API
- Independent resource requests/limits for the Kubernetes egress sidecar
- Unified umbrella release with signed BOM covering all components
Improvements

- Pool capacity exhaustion handling
- Sandbox lifecycle hooks (preStart/periodic) support
Upgrade Notes
Migrate agent-sandbox provider and ingress informer to agents.x-k8s.io/v1beta1 and remove the informer_enabled flag, as the informer-backed cache is now the only Kubernetes read path. Update legacy tag namespaces to the new 1.1.0 scheme. Review the opt-in PostgreSQL snapshot store migration command for your environment.
