// Tests for scripts/release-notes.mjs (#5056): per-server bucketing (one
// server, several, none), sections only for published packages, the
// Repository catch-all dropping no PR, the release-wide Thanks section (laid
// out as the Inspector's) with every exclusion (maintainers by permission,
// bots, deleted accounts, PRs, other repos), keyword parsing, pagination,
// fail-fast at every lookup, and that nothing is created without --draft. Run via
// `npm run test:scripts`.
