- API pages for basic_json_document and basic_json_view, one per member,
and for the four aliases, each with an example
- features/json_view.md: the problem the view solves, ownership and
lifetime, what matches basic_json::parse() and what differs, and when
to choose json, ordered_json, SAX, or the view
- the examples show why one would use the view, not only how: borrowed
vs. owned input, reading a few fields and materializing one subtree,
reusing a document across many messages
- registered in the mkdocs navigation, llms.txt, the docset, the
exceptions page (out_of_range.416), architecture.md, the integration
page, and the README; the yyjson credit is added to the README and
license.md
