readme: v0.4.0 voice pass over a web-1.0 structure

Plain declarative prose throughout the overview and section intros - no
product-page register, no first-person winks. Structure carries the period
feel: top anchor-nav line (middot separators), a dated news line for the
release, --- section rules, and a last-updated footer stamp.

 **AI disclosure:** development here was agentic - Claude Pro plus a local
 open-weight model on a single RTX 5090, as of August–September 2026. This
 project is as much a study of *that process* as it is a port: whether
 current LLMs can carry a codebase like this, and what actually goes wrong
 along the way. Judge the result for yourself.
