Pull request overview
This PR adds comprehensive test coverage for CJS cross-chunk symbol resolution, testing various combinations of chunk types (Entry/Common), wrap kinds (Cjs/Esm/None), output exports (Default/Named), and export access patterns (default/named). The tests verify that symbols from other chunks are accessed correctly in CJS output format, based on the logic in module_finalizers/mod.rs.
Changes:
- Added 9 new test cases covering different combinations of chunk export scenarios
- Added comprehensive README.md documenting the test matrix, code branches, and discovered bugs
- Updated snapshot file to include hash outputs for new tests
