chore(release): publish to npm with trusted publishing

Publish on release:published from release.yml so the npm trusted publisher can
be keyed on the filename, drop NODE_AUTH_TOKEN in favour of id-token: write
(OIDC), run on Node 24 with npm@latest (trusted publishing needs npm >= 11.5.1),
check out the release tag without persisted credentials. GitHub pre-releases go
to the beta dist-tag. The GitHub Packages job gains the packages: write
permission it was missing and publishes with the job's own token instead of a
personal token. package.json gains the repository field that provenance
validation requires.
