Proposal to integrate the plugin with additional skills

The main task here is definitely to interview the user for a new website and develop a fresh theme, which is handled by the provided skill of `site specification`.

I believe, that other skills should integrated:
- Anthropics' [Frontend Design](https://github.com/anthropics/skills/tree/main/skills/frontend-design)
- Microsoft's [Playwright CLI](https://github.com/microsoft/playwright-cli/tree/main/skills/playwright-cli)

That will make the main skill more efficient and productive.

Regards,

Start by reading the provided `site specification` skill and the linked Anthropic Frontend Design and Microsoft Playwright CLI skill resources. Determine how those skills should support the new-website workflow; done means both proposed skills are integrated and the main skill becomes more efficient and productive.
