fix(webpack/react): deduplicate lazy bundles for same file imported via different paths

[orionmiz]

(WIP)

When the same file is imported via different relative paths (e.g., ./Foo.jsx
from index.jsx and ../Foo.jsx from subdir/importer.jsx), they now produce
a single bundle instead of duplicates.

The fix extends the asyncChunkName hook to receive ChunkGroup information,
allowing the ReactWebpackPlugin to normalize chunk names based on resolved
module paths rather than raw import strings.

Closes: #455
