fix: wire Testkube into the base controllers kustomization

[devantler]

🤖 Generated by the Daily AI Assistant

Implements the maintainer's decision on #47 ("I decide to go with 1" — wire-in).

Problem

k8s/bases/infrastructure/controllers/testkube/ is a complete, self-contained controller (HelmRelease + HelmRepository + namespace + NetworkPolicy + full CRD set + its own kustomization.yaml), but the base controllers kustomization never referenced it. So Testkube rendered into zero clusters, and the README's **Testing** — Testkube _(local/CI only; not deployed to prod)_ was effectively false.

Change

One-line additive edit — add - testkube/ to k8s/bases/infrastructure/controllers/kustomization.yaml (placed alphabetically in the t… group).

This routes exactly as the README intends:

• docker (local/CI) provider includes the whole base controllers dir (- ../../../../bases/infrastructure/controllers/) → now deploys Testkube.
• hetzner (prod) overlay enumerates base controllers explicitly and opts out of unused ones → it does not list testkube/, so prod stays opted out.

Validation

kubectl kustomize builds clean and deterministic, with Testkube wired in local/CI only:

overlay	build	testkube resources
k8s/providers/docker/.../controllers/ (local/CI)	OK	17 (present)
k8s/providers/hetzner/.../controllers/ (prod)	OK	0 (opted out)
k8s/bases/.../controllers/	OK	17

ksail workload validate renders the rest of the tree fine. Two caveats, both pre-existing / not introduced by this change:

1. Testkube Helm render is skipped — the chart resolves to an OCI ref (oci://…/testkube:2.9.5) that ksail's renderer can't pull without a registry client, so the HelmRelease is validated as-is (a warning, not a failure). This is a Testkube chart-packaging quirk, independent of the wiring.
2. ksail workload validate flakes non-deterministically on the bases/docker controller groups with YAML-corruption errors (could not find expected ':', mapping values are not allowed) — this is the known kubeconform#363 buffer-aliasing race (varying failure counts across identical runs; kubectl kustomize is always clean). The validate-scaffold gate may therefore need a re-run; it does not indicate a defect in this change.

Size

Small / additive / behaviour-preserving for prod (byte-identical hetzner output).

Fixes #47

Poem

A bunny hops in, adds one line with flair,
testkube/ joins the resource list there.
One entry, one hop, nothing more to declare,
The kustomization grows beyond compare!
