ci(release): pack on pull requests and publish from family tags

Each sequence gets its own workflow so the two version models never meet in one
file. Pack runs without credentials on every pull request and master push, so a
pull request proves the whole publish set still packs; publication is a manual
dispatch guarded by the npm-publish environment, runs only from that family's
tag, and never builds - it uploads the bytes pack produced.

+# packages are separate sequences with their own workflows and version lines.
