Create PureStack sites with a guided wizard

This PR adds PureStack Studio, a wizard that opens in your browser and walks you through creating a new PureStack site. Run npx purestack@latest init, answer a few questions, and you get a working site you can browse straight away.

What you can do now

• Set up a site step by step. Give it a name, choose where to save it, pick a template, adjust its options, and decide whether to install dependencies and set up Git.
• See your site right away. When it's created, Studio opens a live version of your site, and it updates as you make changes.
• Skip the wizard if you prefer. purestack init my-site --yes creates a site directly from the terminal.
• Know what to do next. Studio and the terminal both show the next commands to run.

A better starter template

The starter template has been redesigned so new sites are useful from the beginning:

• a polished landing page with a new look
• a short guide and checklist for making the site your own
• a clearer footer and theme
• instructions for both people and AI agents

Smoother setup

• Creating a site works on Windows, macOS and Linux, including machines without Yarn installed.
• Newly published packages install straight away, without Yarn's one-day waiting period.
• A harmless but confusing warning no longer appears when starting a site on newer Node versions.

Behind the scenes

• Every change is checked automatically on Windows, macOS and Linux, now using Node 26.
• The checks also create a real site from the starter template, as a user would, and confirm it builds and publishes.
• New documentation explains the wizard and how templates work, with screenshots.
• All packages are updated to version 1.1.20.
