33 tests covering rendering, user interactions (userEvent clicks), prop
callbacks, filter state, and conditional description text. Adds a
matchMedia stub to the vitest setup file so components importing
useTheme don't throw in jsdom. Also adds actionlint and zizmor
pre-commit hooks for GitHub Actions linting.

Install @testing-library/react, @testing-library/jest-dom,
@testing-library/user-event, and jsdom. Configure Vitest with globals,
jsdom environment, and a setup file importing jest-dom matchers. Add a
custom render helper wrapping components with QueryClientProvider and
MemoryRouter. Exclude e2e/ from vitest. Smoke test covers
formatEvolutionMethod.
