The Ingress/Egress field docs claimed "an empty list denies all ingress/egress",
which is a false security guarantee. A SecurityGroup projects onto a
CiliumNetworkPolicy that only ADDS allow rules, and Cilium policies are additive
over the tenant's blanket-allow baseline, so an empty list does not isolate a
pod — effective connectivity stays open. Deny / default-deny enforcement depends
on the default-deny baseline, which is separate future work.
Rewrite the API field docs to the accurate semantics, regenerate the OpenAPI so
the served schema description matches, and fix the one DESIGN.md sentence that
still asserted "denies all traffic" (it already contradicted its own safety
section, which correctly states the API cannot deny anything today).

Give each SecurityGroup its own membership label
(securitygroup.sdn.cozystack.io/<name>) and select it from the backing
CiliumNetworkPolicy, instead of deriving the endpointSelector from a single
app's lineage labels. spec.targetRef becomes spec.attachments, so one
SecurityGroup can apply to several applications at once.
Peers move from free-form fromEndpoints/toEndpoints selectors to
fromApp/toApp (resolved to lineage labels) and fromSG/toSG (resolved to
another group's membership label, a reference the Cilium dataplane resolves
live). Attachments are persisted in a storage-owned CiliumNetworkPolicy
annotation, round-tripped and hidden from the SecurityGroup view like the
marker label. Validation now covers attachments and app/SG peers and rejects
names that collide with reserved Cilium entities.
The membership labels are maintained by a separate controller added in a
follow-up commit; this change covers the API types and the
aggregated-apiserver projection only.
BREAKING CHANGE: SecurityGroup spec.targetRef is replaced by
spec.attachments, and ingress/egress peers use fromApp/fromSG/toApp/toSG
instead of fromEndpoints/toEndpoints. The feature is unreleased, so no
migration is required.

Replace the tenant-authored endpointSelector on SecurityGroup with a
targetRef that references a managed application by {apiGroup, kind, name}.
The backing CiliumNetworkPolicy's endpointSelector is now derived by the
API server from the application's lineage labels
(apps.cozystack.io/application.{group,kind,name}) instead of copied from
tenant input, so the selector is machine-generated and can only ever
match the referenced application's own pods in the tenant's namespace.
The in-tree CiliumNetworkPolicy mirror gets its own spec type carrying a
concrete endpointSelector; the ingress/egress rule lists still project
1:1. Reads reconstruct the targetRef from the derived matchLabels, which
is lossless because validation caps each component at a valid label value
below the lineage webhook's truncation threshold.

Introduce the sdn.cozystack.io/v1alpha1 API group with the SecurityGroup
resource. SecurityGroup is a namespace-scoped, tenant-facing firewall
object whose spec mirrors the subset of the CiliumNetworkPolicy rule that
the abstraction exposes (endpointSelector, ingress, egress, ports, CIDR,
FQDN), so the resource can be projected 1:1 onto a CiliumNetworkPolicy
without granting tenants direct access to the cilium.io API group.

Introduce a read-only, namespaced virtual resource
core.cozystack.io/v1alpha1 Option that serves named lists of dropdown
options for the dashboard. Each object (one per source: gpu,
instancetype, instanceprofile, network, image, storagepool,
storageclass, vmdisk, backupclass) is computed on read by an in-process
provider using a privileged dynamic client, so tenants need no direct
access to Nodes, the KubeVirt CR, cluster instancetypes, etc.
Tenants get read access via the aggregated cozy:tenant roles; the
apiserver ServiceAccount gains read on the underlying sources.

The applyconfiguration code referenced testing.TypeConverter from
k8s.io/client-go/testing, which was removed in client-go v0.34.1.
Root cause: hack/update-codegen.sh called gen_helpers and gen_openapi
but not gen_client, so applyconfiguration was never regenerated after
the client-go upgrade.
Changes:
- Fix THIS_PKG from sample-apiserver template leftover to correct
module path
- Add kube::codegen::gen_client call with --with-applyconfig flag
- Regenerate applyconfiguration (now uses managedfields.TypeConverter)
- Add tests for ForKind and NewTypeConverter functions

Replace the chart field with chartRef for referencing Helm charts via
ExternalArtifact resources. This enables the Package controller to
manage chart sources centrally.
Changes:
- Add chartRef field to CozystackResourceDefinition spec
- Remove chart field (deprecated)
- Remove validation (moved to controller)
- Update lineage mapper for new field structure
- Regenerate openapi specs
