ci: re-trigger after CiliumNetworkPolicy fix (homelab PR #49)

CI runner (Forgejo DinD) runs jobs as Docker containers — no in-cluster
SA token available. Industry standard: dedicated SA with minimal RBAC,
long-lived token as KUBECONFIG_B64 secret in Forgejo.

SA: ci-tekton-trigger (namespace: api)
Permissions: create/get/watch/delete PipelineRuns, get TaskRuns, get pod logs
Token: kubernetes.io/service-account-token secret

+# Tekton Integration Tests
+
+Curl-based integration tests for the API gateway, orchestrated by Tekton.
+
+## How It Works
+
+```
+CI pushes image:sha → creates PipelineRun → Tekton spins up gateway sidecar
+→ runs curl tests → reports pass/fail → CI promotes to :latest if pass
+```
+
+The Task runs the gateway image as a **sidecar** (same pod, localhost),
+then executes `scripts/integration-test.sh` which tests every adapter
+via `X-Service` + `X-Resource` header routing.
+
+## Files
+
+| File | Purpose |
+|------|---------|
+| `task-integration-test.yaml` | Task: sidecar gateway + curl test step |
+| `pipeline-integration-test.yaml` | Pipeline: wraps the Task |
+| `scripts/integration-test.sh` | Test script (mounted as ConfigMap) |
+| `kustomization.yaml` | Generates ConfigMap from script |
+
+## Manual Run
+
+```bash
+kubectl apply -k k8s/tekton/
+kubectl create -f - <<'EOF'
+apiVersion: tekton.dev/v1
+kind: PipelineRun
+metadata:
+  name: integration-test-manual

+    value: forgejo.riotpiao.com/rock/api-gateway:latest
+EOF
+
+# Watch
+kubectl logs -f -n api pipelinerun/integration-test-manual -c step-run-tests
+```
+
+## Updating Tests
+
+Edit `scripts/integration-test.sh`, then:
+
+```bash
+kubectl apply -k k8s/tekton/   # recreates ConfigMap
+```
+
+## Tekton Infrastructure
+
+Tekton Pipelines is installed in `~/workplace/homelab` via ArgoCD
+(`k8s/argocd/apps/06-ci-cd.yaml` → vendored `k8s/infra/tekton/release.yaml`).
