Add llms.txt generation for LLM-optimized documentation export

[Copilot]

Implements opt-in generation of llms.txt - a single-file export combining all markdown content in navigation order for LLM consumption.

Changes

Type system

• Added llms?: boolean to HyperbookJson config schema

Build process

• Generates llms.txt when enabled, with format: <SYSTEM>BookName - Version X.X.X</SYSTEM> header followed by all page content
• Respects navigation ordering (index property), automatically excludes hide: true pages/sections
• Optimized to load all files once instead of per-page

Documentation

• Updated English and German config docs with llms property description

Example

{
  "name": "My Documentation",
  "llms": true
}

Produces llms.txt:

<SYSTEM>My Documentation - Version 0.62.0</SYSTEM>

# Chapter 1
Content here...

# Chapter 2
Content here...

Original prompt

Generate a llms.txt file when the key "llms" is true. in the hyperbook config.

The file you basicly combine all markdown files in this file. The title of the file should be the name of the hyperbook and its version.

hyperbook name - Version 0.0.0

Also make sure that everything has the same order as in the hyperbook. Also ignore pages and sections with hide: true.

Also update the documentation and add a changeset
