Jarred Sumner e3c25260ed feat(bundler): add configurable CJS→ESM unwrapping via unwrapCJSToESM ...

Add `minify.unwrapCJSToESM` JS API option and `--unwrap-cjs-to-esm` CLI
flag to force CJS-to-ESM conversion for specific packages, eliminating
the `__commonJS` wrapper. Supports wildcard patterns (e.g. `"@scope/*"`).
User entries extend the default React family list.

Also removes the react/react-dom version check that gated conversion,
and fixes `packageName()` to handle scoped packages (`@scope/pkg`).
