NODE_AUTH_TOKEN expired (set 90 days ago, the npm token default expiry) causing all publish runs to fail with 'PUT 404 Not Found' since 2026-04-30. Migrate publish.yml and publish-platform.yml to npm Trusted Publishing (OIDC) so we no longer depend on long-lived secrets: - Bump actions/setup-node v4 -> v6 (improves OIDC compatibility) - Add 'npm install -g npm@latest' to guarantee npm CLI >= 11.5.1 (the minimum required for trusted publishing). - Drop NODE_AUTH_TOKEN env from every publish step. The npm CLI picks up the GitHub Actions OIDC token automatically. - Keep --provenance / NPM_CONFIG_PROVENANCE=true (real-world reports indicate provenance is not auto-emitted yet). Per-package trusted publisher must still be configured on npmjs.com (Settings -> Trusted Publisher) for all 24 packages (oh-my-opencode + oh-my-openagent main + 11 platform packages each, dual-published) before the next publish run.
