release.yml's comments sent readers to docs/releasing.md, which never
existed: the workflow was ported from a sibling app without its document.
docs/releasing.md now covers how a release is cut (version bump with
cargo xtask version, the release branch, the draft, publishing, test runs
with a version override), what each job builds and how (macOS universal
signing and notarization, Windows x64/x86/arm64 with the PE checks and the
two signing options, Linux packages and the glibc 2.35 floor behind the
ubuntu-22.04 runners, FreeBSD in a VM, the web build, craft-fonts), the
draft release job and the signing secrets. Every detail is checked against
this repository's workflow and packaging scripts. The README links it.
