e2e-discover

Explore a web project's codebase to discover testable user journeys, then generate YAML test manifests mirroring the UI navigation tree. Use when setting up E2E tests for a new project, or after structural UI changes (new routes, removed pages, navigation updates). Trigger on 'e2e discover', 'generate e2e tests', 'discover test routes', 'update test manifests', 'scan UI for tests'.
