Subject: [PATCH] ci: publish to npm via OIDC Trusted Publishing

Replace the long-lived npm_token (which expired and broke the last
release) with OIDC Trusted Publishing: grant id-token: write, run on
Node 24 with npm >= 11.5.1, and drop NODE_AUTH_TOKEN. Auth is now minted
per-run and publishes carry a signed provenance attestation.
