Add Playwright e2e generator foundation

[Mykidzou]

Summary

Contributes to #13755 ($$ bug-bounty $$, $500) by adding a first-pass Playwright e2e implementation to generator-jhipster.

This PR adds:

• playwright as a selectable client e2e test framework alongside Cypress
• a new jhipster:playwright generator
• generated Playwright config, npm scripts, TypeScript config, ESLint fragment, and README notes
• generated JWT/session account login and logout smoke specs using Playwright locators/API helpers
• focused generator coverage for emitted files, package scripts/dependencies, OAuth2 scoping, namespace lookup, prompt, and composition plumbing

Validation

Passed locally on Windows:

• npm run check-types
• npm run eslint -- generators/playwright generators/client/command.ts generators/client/generator.ts generators/client/generator.spec.ts generators/client/prompts.spec.ts lib/jhipster/test-framework-types.ts lib/jhipster/application-options.ts lib/types/command-all.d.ts generators/types.d.ts
• npx esmocha generators/playwright/generator.spec.ts generators/generate-blueprint/internal/lookup-namespaces.spec.ts --forbid-only
• npm run build
• npm run prettier:check -- generators/playwright generators/client/command.ts generators/client/generator.ts generators/client/generator.spec.ts generators/client/prompts.spec.ts lib/jhipster/test-framework-types.ts lib/jhipster/application-options.ts lib/types/command-all.d.ts generators/types.d.ts .blueprint/github-build-matrix/support/git-changes.ts generators/generate-blueprint/internal/lookup-namespaces.spec.ts
• git diff --check

Notes:

• generators/client/prompts.spec.ts and the client composition spec currently hit the existing Windows ESM loader path issue (Received protocol 'c:') before reaching the Playwright assertions. The new Playwright generator spec and typecheck cover the added behavior directly.

Scope

Intentionally in scope for this first increment:

• generator selection/composition
• runnable Playwright project setup
• account login/logout smoke coverage for JWT and session apps
• lint/type/test coverage for the generator output

Intentionally out of scope for this increment:

• OAuth2 browser flow generation
• generated entity CRUD Playwright specs
• replacing or removing Cypress
• CI provider-specific Playwright wiring

Hi, I opened a focused implementation for #13755 adding a new Playwright generator, prompt/namespace wiring, generated config/scripts/docs, and smoke specs for JWT/session login/logout. Local validation passed: check-types, focused eslint, focused esmocha, build, prettier check, and git diff --check. Happy to adjust scope if maintainers prefer a smaller first pass.

Pull request overview

Adds an initial Playwright-based end-to-end testing generator to generator-jhipster, integrating it as a selectable client e2e framework alongside Cypress and wiring up the generated project scaffolding (config, linting, scripts, and smoke specs).

Changes:

• Introduces a new jhipster:playwright generator with templates for Playwright config, ESLint fragment, TS config, support helpers, and account login/logout smoke specs.
• Extends client prompting/selection + composition so Playwright can be chosen and composed like Cypress.
• Updates shared typings/options + internal namespace lookup/build-matrix change detection to recognize the new generator.

Hi! I reproduced the failing check-npm-test from this PR locally.

The red path looks like snapshot drift after adding the new jhipster:playwright namespace, plus the generated generators/types.d.ts ordering from update-generators.

I have a small local patch that:

• updates the affected generator/helper snapshots,
• adds the missing git-changes snapshot for generators/playwright/index.ts,
• refreshes generators/types.d.ts via update-generators.

Focused validation passes locally:

npx esmocha --no-insight --no-parallel generators/angular/generators/bootstrap/generator.spec.ts generators/client/generators/bootstrap/generator.spec.ts generators/ci-cd/generator.spec.ts generators/angular/generator.spec.ts generators/react/generator.spec.ts generators/react/generators/bootstrap/generator.spec.ts generators/spring-boot/generator.spec.ts generators/vue/generator.spec.ts generators/vue/generators/bootstrap/generator.spec.ts .blueprint/github-build-matrix/support/git-chages.spec.ts lib/testing/helpers.spec.ts .blueprint/update-generators/generator.spec.ts --forbid-only

Result: 4372 passing, 110 pending.

Happy to open this as a small follow-up PR or share the patch if useful.
