Fix "require is not defined" caused by dist/package.json type:module

ncc injects {"type":"module"} into dist/package.json when the source project is ESM, but the bundle itself is CJS format. Node then tries to run it as ESM and fails.

Add a postbuild hook that overwrites dist/package.json with {} to establish a CJS package boundary in dist/ without walking up to the root package.json.
