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.

George J.

Comienza leyendo la skill `site specification` proporcionada y los recursos enlazados de Anthropic Frontend Design y Microsoft Playwright CLI. Determina cómo deberían esas skills respaldar el flujo de trabajo de new-website; el trabajo estará terminado cuando ambas skills propuestas estén integradas y la skill principal sea más eficiente y productiva.
