Replace tools/release.mjs with two workflow_dispatch flows:
- stable: production environment gate (Required Reviewers) + lightweight git tag. Trusted Publishing (OIDC) removes the need for an npm token.
- channel beta: disposable 0.0.0-beta-<sha>-<date> versions on the corresponding dist-tag, no tag, no commit. Any collaborator can dispatch without npm credentials.
Pack-time scans via publint, attw, gitleaks; weekly Dependabot for npm + actions.
