Clarify runtime-backed SDK publishing

[MackinnonBuck]

Summary

• clarify runtime-backed workflow job names as SDK package build/publication operations
• align retained-manifest publishing with the established npm/Azure behavior: validate locally, publish the exact nine tarballs sequentially with the umbrella package last, accept only recognized idempotent conflicts, and fail other publish errors
• remove registry readback, dist-tag repair, and internal clean-install verification from runtime-backed publication
• add focused helper and workflow tests for functional publishing behavior

Validation

• cd nodejs && npm test -- test/npm-release.test.ts (17 tests passed)
• cd nodejs && npx prettier --check scripts/npm-release.js test/npm-release.test.ts
• cd nodejs && npx eslint scripts/npm-release.js test/npm-release.test.ts
• cd nodejs && npm run typecheck
• YAML parse with js-yaml
• git diff --check

actionlint and whole-workflow Prettier reproduce only pre-existing baseline findings around concurrency.queue support and workflow formatting.
