Add hyperbook.new command to VSCode extension

[Copilot]

Implements hyperbook.new command for creating Hyperbook projects directly from VSCode, using a multi-step QuickInput wizard. Adds platform selection (GitHub, GitLab, EduGit, Vercel, Custom) to the creation workflow.

Changes

• New @hyperbook/create package: Extracts creation logic into reusable library

  • Environment-agnostic core (no process.exit, console output handled by callers)
  • Handles file operations, git init, template copying
  • Returns structured results for error handling

• VSCode command (hyperbook.new): 8-step wizard for project creation

  • Folder selection, project metadata (name, description, author)
  • License picker (CC variants, custom)
  • Language code with validation
  • Platform selection for publishing intent

• CLI refactor: Updated hyperbook new to use @hyperbook/create, maintaining existing UX while adding platform selection step

Example

// VSCode extension usage
const result = await createHyperbook({
  bookPath: "/path/to/my-book",
  name: "my-book",
  description: "A new hyperbook",
  platform: "github",
  license: "cc-by",
  language: "en"
});

Command accessible via Command Palette (Ctrl+Shift+P) → "Hyperbook: Create new Hyperbook"

This section details on the original issue you should resolve

<issue_title>Create hyperbook from VS Code extension</issue_title>
<issue_description>We should add a new command hyperbook.new for creating a new hyperbook. It should work the same as the cli application. Therefore, we need to implement something similiar to this: https://github.com/microsoft/vscode-extension-samples/tree/main/quickinput-sample

We should also add a step for asking a platform for publishing: (GitHub, GitLab, EduGit, Vercel or custom).

Maybe we can extract the functionality of creating a new hyperbook of the hyperbook package into a new package to keep the cli and the vs code extension in sync.</issue_description>
