Add --provenance --access public flags to npm publish for OIDC trusted publisher support

Summary:
OIDC Trusted Publishers was failing with 404 errors when publishing to npm. Switch to token-based auth using NPM_TOKEN secret instead.

Changes:
  - Replace yarn publish with npm publish (yarn doesn't use .npmrc auth from actions/setup-node)
  - Use NPM_TOKEN secret for authentication instead of OIDC
  - Remove id-token permission (no longer needed)

Requires adding an NPM automation token as the NPM_TOKEN secret in GitHub repo settings.
