- Move docs to docs/; keep areas for prompts only
- Relocate Makefile to scripts/Makefile; update docs to use it
- Move ci.Dockerfile to docker/ci.Dockerfile; update compose
- Move commitlint config to .config and update hook
- Remove root AGENTS.md (use area AGENTS.md)

+Local CI Parity & Bootstrap
+
+Purpose
+- Provide a portable CI toolchain via a Dockerized image and compose file so that format/lint/build checks run identically locally and in CI.
+
+Components
+- `docker/ci.Dockerfile` – builds the CI image with shellcheck, shfmt, hadolint, actionlint, yamllint, Node tools.
+- `docker/ci.compose.yml` – runs the CI container mounting the repo at `/workspace`.
+- `scripts/ci` – wrapper for phases: `format`, `lint`, `build`, `test`, `security`, `all`.
+- Git hooks – `.githooks/*` installed via `scripts/setup-hooks`.
+
+Usage
+- Install hooks: `make -f scripts/Makefile hooks-setup`
+- Quick checks: `make -f scripts/Makefile quick` (format + lint)
+- Full pass: `make -f scripts/Makefile check` (all phases)
+
+Notes
+- Pre-commit hook runs format/lint and commit message checks.
+- Pre-push hook runs build/test/security placeholders.
+- CI workflow runs on integration and protected branches when runners are enabled.
