feat: configure Vercel to wait for CI before deploying

- Update GitHub Actions CI workflow to use Node 22
- Add architecture and deadcode checks to CI pipeline
- Create Vercel deployment guard script
- Add comprehensive deployment documentation
- Update README with CI badge and quality gates info
- Configure vercel.json for deployment settings

Vercel will now only deploy to production after all CI checks pass:
- Linting & formatting
- Type checking
- Tests
- Build verification
- Architecture validation
- Dead code detection

See DEPLOYMENT.md for configuration instructions.

+# Deployment Configuration
+
+This document explains how to configure Vercel to only deploy when GitHub Actions CI passes.
+
+## Overview
+
+The project is configured to run comprehensive CI checks on every push and pull request:
+
+- **Linting** - Code style and quality
+- **Type checking** - TypeScript validation
+- **Tests** - Unit and integration tests
+- **Build** - Production build verification
+- **Architecture** - Dependency rules validation
+- **Dead code** - Unused code detection
+
+Vercel should only deploy after all these checks pass on the main branch.
+
+## Configuration Options
+
+There are two ways to prevent Vercel from deploying when CI fails:
+
+### Option 1: Vercel Deployment Protection (Recommended)
+
+This is the simplest and most reliable approach.
+
+1. **Enable Deployment Protection in Vercel:**
+   - Go to your Vercel project settings
+   - Navigate to **Git** → **Deployment Protection**
+   - Enable **"Wait for Checks to Complete"**
+   - This makes Vercel wait for all GitHub status checks before deploying
+
+2. **Configure Branch Protection (GitHub):**
+   - Go to GitHub repository settings
+   - Navigate to **Branches** → **Branch protection rules**
+   - Add rule for `main` branch
+   - Enable **"Require status checks to pass before merging"**
+   - Select all CI jobs: `lint`, `type-check`, `test`, `build`, `architecture`, `deadcode`
+   - Enable **"Require branches to be up to date before merging"**
+
+This ensures:
+- ✅ PRs cannot be merged unless CI passes
+- ✅ Vercel waits for CI to complete before deploying
+- ✅ Production always has passing CI
+
+### Option 2: Ignored Build Step (Advanced)
+
+Use a custom script to check CI status before building.
+
+1. **Add GitHub Token to Vercel:**
+   - Go to Vercel project settings
+   - Navigate to **Environment Variables**
+   - Add `GITHUB_TOKEN` with a Personal Access Token
+   - Scope: `repo:status` (read commit status)
+   - Apply to: Production, Preview, Development
+
+2. **Configure Ignored Build Step:**
+   - Go to Vercel project settings
+   - Navigate to **Git** → **Ignored Build Step**
+   - Set custom command:
+     ```bash
+     bash scripts/vercel-should-deploy.sh
+     ```
+
+3. **How it works:**
+   - Script checks if CI has passed via GitHub API
+   - Exit code 0 = skip build (CI failed/pending)
+   - Exit code 1 = proceed with build (CI passed)
+   - Preview deployments always proceed
+   - Production deployments wait for CI
+
+## Deployment Workflow
+
+### For Pull Requests (Preview)
+1. Push commits to PR branch
+2. GitHub Actions runs CI checks
+3. Vercel creates preview deployment (regardless of CI status)
+4. CI status is shown on PR
+5. Can only merge if CI passes (branch protection)
+
+### For Production (Main Branch)
+1. PR is merged to `main`
+2. GitHub Actions runs CI checks
+3. **Vercel waits for CI to complete** (if Deployment Protection enabled)
+4. Once CI passes, Vercel deploys to production
+5. If CI fails, deployment is blocked
+
+## CI Jobs
+
+The following jobs must pass for deployment:
+
+| Job | Description | Blocks Deploy |
+|-----|-------------|---------------|
+| `lint` | ESLint + Biome formatting | ✅ Yes |
+| `type-check` | TypeScript compilation | ✅ Yes |
+| `test` | Vitest unit tests | ✅ Yes |
+| `build` | Production build | ✅ Yes |
+| `architecture` | Dependency rules | ✅ Yes |
+| `deadcode` | Unused code detection | ⚠️ Warning only |
+
+## Manual Deployment Override
+
+If you need to deploy even when CI fails (emergency hotfix):
+
+1. **Temporarily disable branch protection:**
+   - GitHub → Settings → Branches → Edit rule
+   - Uncheck "Require status checks to pass"
+   - Merge PR
+   - Re-enable protection immediately after
+
+2. **Or push directly to main** (not recommended):
+   ```bash
+   git push origin main --no-verify
+   ```
+
+## Troubleshooting
+
+### Vercel deploys even though CI failed
+
+**Solution:** Enable "Deployment Protection" in Vercel settings.
+
+### CI is stuck in pending state
+
+**Solution:** Check GitHub Actions workflow logs. Ensure all jobs complete.
+
+### Preview deployments are blocked
+
+**Solution:** Preview deployments should never be blocked. Check Ignored Build Step script logic.
+
+### Need to deploy urgently
+
+**Solution:** Use manual override (see above), but fix CI issues immediately after.
+
+## Best Practices
+
+1. ✅ Always ensure CI passes before merging
+2. ✅ Use preview deployments to test changes
+3. ✅ Fix CI failures immediately - don't merge broken code
+4. ✅ Review CI logs when checks fail
+5. ❌ Don't bypass CI unless absolutely necessary
+6. ❌ Don't merge with failing tests "to fix later"
+
+## Verification
+
+To verify the setup is working:
+
+1. Create a PR with intentionally broken code (e.g., TypeScript error)
+2. Verify CI fails
+3. Verify PR cannot be merged
+4. Verify Vercel deployment is blocked/skipped
+5. Fix the code
+6. Verify CI passes
+7. Verify PR can be merged
+8. Verify Vercel deploys successfully
+
+## Environment Variables
+
+Required environment variables in Vercel:
+
+| Variable | Required For | Description |
+|----------|--------------|-------------|
+| `GITHUB_TOKEN` | Option 2 only | GitHub Personal Access Token with `repo:status` scope |
+
+Not needed for Option 1 (Deployment Protection).
+
+## Status Badge
+
+Add to README.md to show CI status:
+
+```markdown
+[![CI](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/ci.yml/badge.svg)](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/ci.yml)
+```
+
+## Summary
+
+**Recommended Setup:**
+1. Enable Vercel "Deployment Protection" (wait for checks)
+2. Enable GitHub branch protection for `main`
+3. Require all CI jobs to pass before merging
+
+This ensures production always has high-quality, tested code.
