[Brentlok]

Summary by CodeRabbit

• Tests

  • Added end-to-end Playwright tests, fixtures, a global setup to prepare browser artifacts, and a new test script to run E2E suites.

• Chores

  • Added Playwright as a dev dependency and updated CI to install browsers.

📝 Walkthrough

Walkthrough

Adds Playwright end-to-end tests and supporting infrastructure to packages/uniwind: Playwright config, global setup that compiles CSS and bundles a browser IIFE, tests and TypeScript globals, package/CI updates, .gitignore entries, and a Jest mapping removal.

Changes

Cohort / File(s)	Summary
E2E Config & Setup packages/uniwind/playwright.config.ts, packages/uniwind/tests/e2e/global-setup.ts, packages/uniwind/tests/e2e/window.d.ts	New Playwright config, globalSetup that compiles Tailwind CSS and bundles a browser IIFE via esbuild, and TypeScript global augmentation exposing window.__uniwind utilities.
E2E Tests packages/uniwind/tests/e2e/getWebStyles.test.ts	New Playwright test that injects compiled CSS and the bundled IIFE, exercising window.__uniwind.getWebStyles and asserting colors and scoped theme behavior (one test skipped).
Package & CI packages/uniwind/package.json, turbo.json, package.json	Adds @playwright/test and test:e2e script; updates turbo to add test:e2e task and precommit dependency; bumps turbo devDependency; CI workflow adds step to install Playwright browsers.
Ignore & Jest packages/uniwind/.gitignore, packages/uniwind/jest.config.web.js	Adds tests/e2e/.generated/, playwright-report/, and test-results/ to .gitignore; removes CSS module mapping from Jest web config.

Poem

🐇 I stitched a stylesheet and bundled a tune,

I hopped through pages under the test-run moon,
Playwright danced and the browser agreed,
Colors and themes delivered at speed,
Hooray — tiny rabbit tests made it bloom! 🌷

In `@packages/uniwind/tests/e2e/global-setup.ts`:
- Line 1: The e2e setup imports and uses esbuild (import { build } from
'esbuild' and await build(...)) but esbuild is not declared in the uniwind
package's devDependencies; add "esbuild" to the uniwind package.json
devDependencies (with a suitable version range) so the import resolves in
isolated installs and CI.
- Line 9: ROOT is currently derived from resolve(process.cwd()), which makes it
depend on where the test runner was invoked; change it to resolve the test
file's directory instead so ROOT is independent of invocation cwd. Replace the
use of process.cwd() when computing ROOT with a directory computed from the
module/file location (e.g., using __dirname in CommonJS or
path.dirname(fileURLToPath(import.meta.url)) in ESM) so the symbol ROOT is
anchored to the global-setup.ts file location rather than the process working
directory.
