chore: add frontend dependencies and update test fixtures

- Add react-router-dom, @tanstack/react-query, zustand, @headlessui/react
- Update pnpm workspace configuration
- Update test fixtures to reference OpenCode instead of RunFusion
- Add frontend environment variable examples
- Update .gitignore for .opencode and .sisyphus directories
