chore: switch to npm trusted publisher with OIDC provenance (#162)

## Summary
- Update release workflow to use `id-token: write` for npm OIDC
authentication (trusted publishers)
- Remove `NPM_TOKEN` secret dependency — auth is now handled via OIDC
- Add `provenance: true` to `publishConfig` in `package.json` and
`--provenance` to release-it `publishArgs`
- Upgrade workflow to Node 22, `actions/checkout@v6`,
`actions/setup-node@v6`
- Use `GH_TOKEN` PAT for checkout/push to bypass branch protection

## Prerequisites
- Configure trusted publisher on npmjs.com for `@yao-pkg/pkg-fetch` →
link to `yao-pkg/pkg-fetch` repo + `release-it.yml` workflow
- Create a `GH_TOKEN` repository secret with a PAT that has push access

## Test plan
- [ ] Verify trusted publisher is configured on npmjs.com
- [ ] Verify `GH_TOKEN` secret is set in repo settings
- [ ] Trigger the workflow manually with `patch` and confirm it
publishes with provenance
