fix(cli): transform yoga-sync.mjs to remove top-level await for CJS

The newer yoga-sync builds from socket-btm use top-level await which
isn't compatible with esbuild's CJS output format. This adds a
transformation step during asset processing to convert the top-level
await pattern back to a promise-based export.
