Sync the complete published `@babel/runtime@8.0.8` helper tree so future updates have a recorded upstream baseline. Import all 95 CommonJS/ESM helper pairs, the MIT license, conditional exports, and `sideEffects: false`. Preserve 26 legacy Babel helper pairs, three TypeScript decorator helper pairs, and existing import paths. 189 of the 191 upstream files are byte-identical. The two `setFunctionName` implementations retain Oxc's existing behavior and match main. Add a hash manifest, a repeatable sync script, CJS/ESM tests in CI, and an async-generator execution regression. No new helper optimizations or correctness patches are included. Validation: upstream hashes, compatibility preservation, sync idempotence and drift refusal, formatting, lint, syntax, and whitespace checks passed. Runtime tests were not rerun after restoring this tree because automatic approval blocked helper execution; the newer Babel fixture revision pinned by main was not run locally. AI assistance: Claude.
