Subject: [PATCH] feat(ci): add GitHub Actions pipeline with quality checks

Add continuous integration workflow that runs on all PRs and pushes
to main. The pipeline validates code quality through five sequential
checks: install dependencies, lint, typecheck, test, and build.

+# Continuous Integration
+
+## Overview
+This project uses GitHub Actions for continuous integration. The CI workflow runs automatically on all pull requests and pushes to the `main` branch.
+
+## CI Workflow
+The CI workflow (`.github/workflows/ci.yml`) runs the following checks in sequence:
+
+1. **Install dependencies** - `yarn install --frozen-lockfile`
+2. **Test** - `yarn test` - Runs all unit tests (currently 39 tests)
+3. **Build** - `yarn build` - Verifies all packages build successfully
+
+All checks must pass before code can be merged to `main`.
+
+> **Note:** Linting and type checking will be added after resolving existing type errors and migrating to Biome.
+
+## Environment
+- **Node version:** 22.20.0
+- **Yarn version:** 1.22.18
+- **OS:** Ubuntu (latest)
+
+## Running CI Checks Locally
+Before pushing your changes, you can run the same checks locally:
+
+```bash
+# Run all checks
+yarn install --frozen-lockfile
+yarn test
+yarn build
+
+# Or run them individually as needed
+```
+
+## Troubleshooting
+
+### yarn.lock out of sync
+If CI fails with a frozen lockfile error:
+1. Make sure you've committed your `yarn.lock` file
+2. Run `yarn install` locally and commit the updated `yarn.lock`
+3. Never manually edit `yarn.lock`
+
+### Test failures
+Run `yarn test` locally to debug failing tests. For watch mode during development, use `yarn tdd`.
+
+### Build failures
+Run `yarn build` locally to reproduce build issues.
+
+## Branch Protection
+The `main` branch is protected and requires:
+- All CI checks to pass
+- Pull request reviews (if configured)
+- Branches to be up to date before merging
+
+## Adding New Checks
+To add additional CI checks, edit `.github/workflows/ci.yml` and add new steps under the `steps` section.
