ci: use GitHub App token for release-please

[FBumann]

Summary

• Use actions/create-github-app-token to generate an app token for release-please
• App token pushes trigger workflow events (unlike GITHUB_TOKEN), so CI runs on release-please PRs
• No PAT needed — tokens auto-expire and commits are attributed to the app, not a person

Test plan

• Merge and verify next release-please PR gets CI checks
