Patch Changes

• #7501 9c09bca - fix(start): emit client entry scripts from the root route manifest. When scriptFormat: 'iife' and the entry chunk has static-import siblings (e.g. an extracted runtime via optimization.runtimeChunk: 'single'), the manifest now includes those async siblings before the async client entry in root route scripts, fixing hydration for IIFE bundles with extracted runtimes.
