ci: fix OIDC publish — drop npm@latest engine break

[omegent-app]

Summary

The Changesets version job failed before publish:

npm error engine Not compatible with your version of node/npm: npm@12.0.1
npm error notsup Required: {"node":"^22.22.2 || ^24.15.0 || >=26.0.0"}
npm error notsup Actual:   {"node":"v24.14.1","npm":"11.11.0"}

npm install -g npm@latest pulled npm 12, which needs Node ≥ 24.15. The runner is on Node 24.14 with npm 11.11.0, which already satisfies OIDC trusted publishing (≥ 11.5.1).

This PR updates .github/release.oidc.yaml (template) to remove that upgrade step.

Maintainer action (bot cannot push workflow files)

After merge, or immediately on main:

# delete these 3 lines from .github/workflows/release.yaml:
#      - name: Ensure npm supports OIDC trusted publishing
#        run: npm install -g npm@latest && npm --version

# or re-copy the fixed template:
cp .github/release.oidc.yaml .github/workflows/release.yaml
git add .github/workflows/release.yaml
git commit -m "ci: remove npm@latest upgrade breaking OIDC publish"
git push

Then re-run the failed Changesets workflow (or wait for the push).

Test plan

• Live release.yaml no longer runs npm@latest upgrade
• Version job reaches publish
• Log shows OIDC path: No NPM_TOKEN found, but OIDC is available - using npm trusted publishing
