Automated Template Testing in CI

[Josephat-S]

[#### What to build

Add a GitHub Actions workflow that generates and builds every template+architecture+design combination to catch regressions. This prevents the "framer-motion not found" type of bugs from reaching users.

Files to create

• .github/workflows/templates.yml
• scripts/test-templates.js

Specs

• Matrix strategy: test all 5 templates × available architectures × 3 key designs (Minimal Clean, Dark Terminal, Glassmorphism).
• Each job: generate project → npm run build (or npx vite build).
• Run on PRs that touch templates/, src/generate.js, or src/dependencies.js.

Acceptance criteria

• CI workflow runs template generation tests on relevant PRs.
• Tests cover all template + architecture combinations.
• Tests cover sidebar=true and sidebar=false variants.
• Tests cover at least 3 design themes.
• Failing template build blocks the PR.

Dependencies

• ISSUE-003: CI/CD & Code Quality. #9
