docs: add llms.txt to docs for AI friendly navigation (#619)

* Add auto-generated llms.txt support for documentation

Configure Hugo to auto-generate llms.txt file following the llms.txt specification
(https://llmstxt.org). The file provides a structured index of all documentation
sections, including summaries from frontmatter, making it easier for LLMs to
understand the documentation structure and content.

- Add outputFormats configuration in Hugo config for text/plain format
- Create index.llms.txt template with dynamic section generation
- Uses frontmatter summary field for page descriptions
- Includes all 92 CLI commands in Reference section
- Optional section for extended context that can be skipped for shorter windows

* add summary frontmatter to support description in llms.txt
