build(scripts): add root-level pnpm run storybook script

Adds a storybook script to the root package.json that filters into
the luna-charts package, so Storybook can be launched directly from
the repository root instead of requiring a manual cd into
packages/luna-charts. Updates README.md to document the new command
as part of the standard developer workflow.

 Closes #11.

+- A dedicated `Dockerfile.test`, based on the official Playwright container
-- `docker-compose.test.yaml` orchestrates the test execution, isolating dependencies from the host system

-- The same containerized environment is used locally by contributors and in Continuous Integration, avoiding "works on my machine" discrepancies caused by differing local Playwright/browser installations

+- Locally, `docker-compose.test.yaml` builds this image from source and
+  orchestrates test execution, isolating dependencies from the host system
+- In Continuous Integration, the same `Dockerfile.test` is built and

+  Playwright version, e.g. `luna-charts-test:v1.62.1`); CI jobs pull this
+  prebuilt image directly rather than rebuilding it on every run, then
+  check out the current commit and install dependencies inside the running
+  container before executing tests
+- `Dockerfile.test` remains the single source of truth for the test
+  environment definition in both cases — only *when* the image is built
+  (on demand locally, ahead of time for CI) differs

+
+### 2026-08-04 – CI uses a prebuilt test image instead of rebuilding per run
+
+**Reason**
+
+The initial implementation of Section 6.6 assumed CI would build
+`Dockerfile.test` fresh on every run, identical to local execution. In
+practice, this required Docker-in-Docker access inside the CI runner
+purely to build a single-service image — disproportionate operational
+complexity (privileged sidecar container, custom pod networking,
+runner-level configuration) for the orchestration value actually needed,
+since `docker-compose.test.yaml` defines only one service with no
+inter-service dependencies.
+
+**Changes**
+
+- Section 6.6 updated to describe the actual CI flow: `Dockerfile.test` is
+  built and pushed to the registry out-of-band (not on every CI run), and
+  CI jobs pull the prebuilt image, then check out the current commit and
+  install dependencies at runtime
+- Clarified that `Dockerfile.test` remains the single source of truth for
+  the test environment definition; only the build trigger differs between
+  local and CI usage
+
+**Impact**
+
+No other architectural decision in this document is affected. Local
+component testing (`pnpm test:component`) is unchanged.

+
+### 2026-08-03 – Continuous Integration: GitHub Actions replaced with Gitea Actions
+
+**Reason**
+
+During implementation, the project moved to a self-hosted Gitea instance
+with Gitea Actions (`act_runner`) instead of GitHub Actions. The ADR's
+"Considered Alternatives" and "Decision" tables still listed GitHub
+Actions, which no longer matched the actual CI/CD tooling in use.
+
+**Changes**
+
+- "Considered Alternatives" table: `Continuous Integration` row updated —
+  considered alternatives changed to *GitHub Actions, GitLab CI, Azure
+  Pipelines, Gitea Actions*; selected technology changed to **Gitea
+  Actions**
+- "Decision" table: **GitHub Actions** entry replaced with **Gitea
+  Actions**
+- "Rationale" section: `GitHub Actions` subsection replaced with `Gitea
+  Actions`, noting that workflows run on a self-hosted `act_runner`
+  (Docker-in-Docker mode) against the project's own Gitea instance
+
+**Impact**
+
+Only the Continuous Integration technology choice is affected. Workflow
+syntax remains GitHub-Actions-compatible (Gitea Actions is designed to be
+largely compatible with the GitHub Actions workflow format), so no other
+architectural decisions in this ADR are impacted.
+
+### 2026-08-04 – Component test CI execution: prebuilt image instead of Docker-in-Docker
+
+**Reason**
+
+Component tests run inside a container built from `Dockerfile.test`
+(based on the official Playwright image). Running this build step inside
+every CI job would require Docker-in-Docker (DinD) access on the
+self-hosted Gitea Actions runner — a privileged sidecar container, custom
+pod networking, and runner-level configuration — solely to build a
+single-service image with no inter-service orchestration need.
+
+**Considered Alternatives**
+
+| Alternative | Description |
+| ----------- | ----------- |
+| Build `Dockerfile.test` fresh on every CI run (DinD) | Mirrors the local `docker compose up --build` flow exactly inside a DinD-enabled CI job. |
+| Replicate `Dockerfile.test`'s steps directly as CI workflow steps, using the public Playwright image | Avoids Docker entirely in CI, but duplicates the test environment definition in two places (`Dockerfile.test` and the workflow YAML), risking drift between local and CI environments. |
+| **Build and push `Dockerfile.test` out-of-band, pull the prebuilt image in CI (selected)** | `Dockerfile.test` remains the only definition of the test environment; the resulting image is built and pushed to the registry separately (tagged by Playwright version), and CI jobs simply pull it and run tests — no Docker access needed at test time. |
+
+Building fresh on every run was rejected due to the disproportionate DinD
+infrastructure complexity for a single-service build. Replicating the
+steps in the workflow file was rejected because it reintroduces a second,
+manually-synchronized source of truth for the test environment.
+
+**Decision**
+
+`Dockerfile.test` is built and pushed to the project's container registry
+out-of-band (not as part of the CI pipeline), tagged by Playwright
+version (e.g. `luna-charts-test:v1.62.1`). The `component-tests` CI job
+pulls this prebuilt image directly, checks out the current commit, and
+runs the test command — no Docker access is required inside the CI job
+container.
+
+**Consequences**
+
+*Positive*
+
+- `Dockerfile.test` remains the single source of truth for the test
+  environment definition
+- No Docker-in-Docker, privileged containers, or custom pod networking
+  required in the CI job itself
+- Faster, simpler `component-tests` job
+
+*Negative*
+
+- The test image must be rebuilt and pushed manually (or via a separate,
+  intentionally-triggered process) whenever `Dockerfile.test` changes;
+  forgetting this step means CI runs against a stale image
+- This is considered an acceptable trade-off given how infrequently
+  `Dockerfile.test` changes, versus the ongoing operational cost of
+  maintaining DinD access in the runner
+
+**Impact**
+
+Local component testing (`pnpm test:component` via Docker Compose) is
+unaffected — it continues to build `Dockerfile.test` fresh via
+`docker-compose.test.yaml`. Only the CI-side image sourcing changes.
