ci: add GitHub Actions CI/CD pipeline

Add single workflow (ci.yml) that runs lint, build, and test
on pull requests, then builds and publishes a container image
to GHCR on master merge. Follows knative/func patterns:
top-level permissions, concurrency groups, version pinning.

Fix ESLint config by removing redundant rule spreads that
re-enabled the base no-unused-vars rule over the TypeScript
version. Add Jest globals for test files.

Downgrade @console/pluginAPI shared dep to >=4.19.0.

Restructure README: move deployment section to the top with
OCP 4.19 prerequisite and GHCR registry link. Add separate
prerequisites for deployment and development sections.

Add hack/next-plan-number.sh for deterministic plan numbering
based on remote PR count.

-## Deployment on cluster
-
-A [Helm](https://helm.sh) chart is available to deploy the plugin to an OpenShift environment.
-
-The following Helm parameters are required:
-
-`plugin.image`: The location of the image containing the plugin that was previously pushed
-
-Additional parameters can be specified if desired. Consult the chart [values](charts/openshift-console-plugin/values.yaml) file for the full set of supported parameters.
-
-### Installing the Helm Chart
-
-Install the chart using the name of the plugin as the Helm release name into a new namespace or an existing namespace as specified by the `plugin.name` parameter and providing the location of the image within the `plugin.image` parameter by using the following command:
-
-```shell
-helm upgrade -i  my-plugin charts/openshift-console-plugin -n my-namespace --create-namespace --set plugin.image=my-plugin-image-location
-```
-
-NOTE: When deploying on OpenShift 4.10, it is recommended to add the parameter `--set plugin.securityContext.enabled=false` which will omit configurations related to Pod Security.
-
-NOTE: When defining i18n namespace, adhere `plugin__<name-of-the-plugin>` format. The name of the plugin should be extracted from the `consolePlugin` declaration within the [package.json](package.json) file.
-
 ## i18n
 
 The plugin uses [react-i18next](https://react.i18next.com/) for translations. The i18n namespace must match

+## 2026-04-20 | Session: CI/CD pipeline and ESLint fixes
+Worked on: GitHub Actions CI/CD pipeline, ESLint config fixes, README restructure
+Completed:
+- Single CI workflow (ci.yml) with three jobs: checks (lint + test), build-image (multi-arch Docker build, no push), publish (build + push to GHCR, master only)
+- Multi-arch builds (amd64, arm64, ppc64le, s390x) via docker/setup-qemu-action + docker/setup-buildx-action, required for OCP
+- Build attestation signing via actions/attest-build-provenance, required for OCP
+- OCI annotations on image index (description, source, vendor, url), following knative/func patterns
+- Docker layer caching via GHA cache (build-image writes, publish reads)
+- Follows knative/func patterns: top-level permissions (id-token, contents, packages, attestations), concurrency groups, cancel-in-progress for PRs
+- Fixed ESLint config: removed redundant rule spreads in src/** block that re-enabled base no-unused-vars over @typescript-eslint/no-unused-vars (all 194 lint errors were config issues, not code issues)
+- Added Jest globals block for test files
+- Downgraded @console/pluginAPI shared dep to >=4.19.0
+- Restructured README: deployment section moved to top with OCP 4.19 prerequisite, GHCR registry link, separate prerequisites for deployment and development
+- Added hack/next-plan-number.sh for deterministic plan/branch numbering based on remote PR count
+- Updated WORKFLOW.md branching convention to use the helper script
+- 8 suites, 34 tests, all passing, zero lint errors
+Left off: PR #10 open. User needs to enable GITHUB_TOKEN write permissions in repo Settings and add branch protection rule for master.
+Blockers: None
