fix(release): npmjs.com shows the English README, and the package metadata names what Codeman is

npm takes the package's readme from an unsorted {README,README.*} glob at
publish time, and with README.zh-CN.md beside README.md it kept picking the
Chinese one, so npmjs.com rendered it. `npm run release` now runs
scripts/npm-release.mjs, which moves README.zh-CN.md to a dot-name for the
length of `changeset publish` and always puts it back (also on a failed or
thrown publish, and after an interrupted earlier run). It lives in the publish
command, not in release.yml, because changesets/action commits the working
tree into its version PR. Verified with npm's own normalize: README.zh-CN.md
before, README.md with the file aside, and the aside copy is never packed.

package.json: the description names the CLIs and says self-hosted (the old
"run 20 autonomous agents" was an internal performance target), and homepage
points at getcodeman.com instead of repeating the repository link.
