Add local e2e testing

[OSpoon]

I attempted to use playwright to write simple test cases. Installed the Playwright Test for VSCode extension in VSCode, and performed simple testing on some templates in the examples directory to ensure consistent display content and proper image loading.

I am trying to automate some tedious manual verifications.

@OSpoon this is looking great – is there anything else you want to add to this PR?

hi @cezaraugusto

There is currently nothing else to add, I've been busy looking for a new job recently, and I don't have much time.

Much needed! Thanks a lot, @OSpoon!
