plan: make the GitHub Actions migration explicit

Call out moving all automation to GitHub Actions as a first-class concern: ci.yml
(phase 1), docs.yml deploy (phase 6), and release.yml publish. Replaces Travis
and the hand-run docs/release scripts.

+## CI/CD: migrate all automation to GitHub Actions
+
+Travis is dead and the docs/release flows are hand-run scripts. Move everything to
+GitHub Actions. Three workflows, landing across the phases they belong to:
+
+- **`ci.yml`** (Phase 1) — on push/PR. Lint + typecheck + unit tests on a Node
+  matrix (18/20/latest). A separate integration job boots `@wordpress/env`, runs
+  `npm run env:seed`, then `test:integration`. Replaces `.travis.yml`.
+- **`docs.yml`** (Phase 6) — on push to `main` (or release tag). Builds the docs
+  (TypeDoc + the new site) and deploys to GitHub Pages, replacing the manual
+  `build/scripts/release-docs.js` → gh-pages flow.
+- **`release.yml`** (Phase 1 scaffold, wired when publishing resumes) — on a
+  version tag / GitHub Release. Builds, tests, and `npm publish` with provenance,
+  replacing the local `release-npm` script. Needs an `NPM_TOKEN` secret.
+
+Keep workflows minimal and legible; use official actions (`actions/checkout`,
+`actions/setup-node`, `actions/deploy-pages`). No third-party actions without a
+pinned SHA.
