fix(ci): configure registry-url and update npm for OIDC publishing (#2)

The OIDC token exchange succeeded during verification but failed during
publish with ENEEDAUTH. This fix:

- Adds registry-url to setup-node action to properly configure OIDC context
- Updates npm to latest version to ensure OIDC trusted publishing support

See: npm/cli#8730
