Add Continuous Integration with GitHub Actions

[crypto-a]

User Story

As a maintainer of the component library
I need a CI workflow using GitHub Actions
So that builds, type checks, and linting run automatically on every push and PR

Details and Assumptions

• Workflow file will be named .github/workflows/ci-build.yaml
• The workflow will run on push and pull_request to main
• The pipeline should include type checking, linting, and Storybook build
• A status badge should be added to the top of README.md

Acceptance Criteria

Given the repository has a GitHub Actions workflow
When a push or pull request is made to the main branch
Then the workflow should automatically run type checking, linting, and Storybook build

Given the README is viewed
Then a badge showing the CI status should be visible and reflect the latest build status
