The Workflow section still described branching from `main` and merging
straight to it. It now describes what the repo actually does: one branch
and one PR per issue cut from and based on `next`, squash-merged into
`next` on a passed independent review, with `main` reached only by the
per-milestone PR from `next` and releases tagged from `main`.
Status and Next Step were stale (they named a branch that landed as
`23aeae4`). Status now points at the 1.0.0 milestone in flight and the
tracker as the authoritative backlog; Next Step names a real open item.
Future Steps keeps only work that has no issue of its own.
