Aleksei Sviridkin 7ab940f309 feat(kubernetes): expose ouroboros as a per-tenant addon
Adds the OuroborosAddon typedef, addons.ouroboros knob, and tenant
HelmRelease that deploys the cozy-ouroboros chart inside a tenant
Kubernetes cluster via the host's flux-helm-controller and the tenant
admin-kubeconfig — same shape as the cert-manager addon.

The HelmRelease overrides controller.mode back to coredns-import
because tenants run the cozystack-coredns wrapper (which carries the
`import /etc/coredns/custom/*.override` directive); the parent chart's
default of mode=coredns is the right shape only for the Talos-managed
host CoreDNS. controller.gatewayApi.enabled is mirrored from the
per-tenant addons.gatewayAPI.enabled — forcing --gateway-api on a
tenant without Gateway-API CRDs CrashLoops the controller on
WaitForCacheSync against missing GVRs. dependsOn grows a conditional
gateway-api-crds entry on the same gate.

controller.clusterDomain is intentionally NOT pre-set by the wrapper.
The chart auto-detects it inside the controller pod by parsing
/etc/resolv.conf — the search list of which is `*.<ns>.svc.<domain>`
and reflects exactly the zone the tenant CoreDNS actually serves
(governed by KamajiControlPlane.spec.networkProfile.clusterDomain
defaulting to `cluster.local`, and the cozystack-coredns wrapper
kubernetes-plugin zone, also `cluster.local`). Pre-setting from a
host-side fact like `_cluster.cluster-domain` would override the
auto-detect with a value that does not match what the tenant kube-dns
serves, silently emitting NXDOMAIN-bound rewrites. Operators that run
a tenant on a non-default cluster-domain can still override via
addons.ouroboros.valuesOverride.ouroboros.controller.clusterDomain.

If addons.ouroboros.enabled is true but ingressNginx is off, the
HelmRelease fails the render with a clear error rather than silently
skipping — the hairpin fix has nothing to fix against without
ingress-nginx, and a no-op addon that quietly does nothing is harder
to debug than an explicit render-time error.

The valuesOverride gateway-api guard accepts every truthy spelling
Helm/YAML emit (bool true, string "true"/"True"/"TRUE", numeric 1,
YAML "yes"/"Yes"/"YES"/"on"/"On"/"ON"/"y"/"Y") via
toString-then-lower-then-string-compare; direct bool eq would error
on type mismatch when an operator passes the value as a string from
--set, and case-insensitive folding catches `--set ...=On` /
`--set ...=True` that pure-lowercase comparison would miss.

The acknowledgeUncleanRemoval gate is defence-in-depth for the rare
edge case where helm uninstall fails to land cleanly (tenant
unreachable, hook timeout, manual kubectl delete bypassing helm) —
in the normal path the upstream chart's pre-delete cleanup hook
(coredns-cleanup-hook.yaml, vendored at 0.6.0) nulls the
ouroboros.override key automatically when the HelmRelease is
uninstalled. The gate only blocks render when a leftover HelmRelease
on the host kube-apiserver shows the previous install is still
sitting on the cluster.

The component is also registered in the kubernetes-application
PackageSource (as kubernetes-ouroboros at path system/ouroboros) so
the tenant HelmRelease's ExternalArtifact resolves.

make generate re-emitted README.md, values.schema.json, the Go struct
+ deepcopy, and the kubernetes-rd ApplicationDefinition openAPISchema
in lockstep.

helm-unittest covers: render gating on enabled flag, hard-fail when
ingress-nginx is off, namespaces and labels, chartRef, dependsOn
cilium/coredns/ingress-nginx + conditional gateway-api-crds, default
coredns-import mode, valuesOverride precedence, gateway-api flag
mirroring in both directions, gateway-api truthy-spelling acceptance
(including case-insensitive on/On/True/TRUE), the lookup-driven
acknowledge gate (kubernetesProvider mock asserts the failedTemplate
path when a prior HelmRelease still exists on the host), the
lookup-returns-nil CI/dry-run path (render proceeds when the cluster
mock has no objects), the _namespace.etcd-empty render gate, and
that controller.clusterDomain is NOT pre-set in the rendered
HelmRelease (so chart auto-detect runs).
