E2E: Implement Smoke Test for Homepage

[EJM143]

Description

As a developer, I want to ensure that the application builds and deploys successfully so that users can access the main landing page without crashing.

We need to add a simple Playwright test that visits the homepage and verifies that the main critical elements render.

Tasks

• Install Playwright (if not already installed).
• Create a new test file tests/smoke.spec.js (or similar).
• Write a test that visits the root URL /.
• Assert that the main "h1" title is visible.
• Assert that the page title (browser tab) is correct.

Acceptance Criteria

• Test passes locally using npx playwright test.
• Test verifies the presence of the main specific header text (e.g., “Welcome to My Portfolio”).
• Test fails if the application returns a 404 or blank page.
