Summary

  • When ensure_lazy_module_initialization_order transfers CJS init calls to a non-wrapped module, the PrependRenderedImport mutations were applied using prepend() (push_front), which reversed the order of multiple init calls.
  • Changed to append_intro() (push_back) to maintain correct insertion order.

Closes #8863

Test plan

  • Added regression test in crates/rolldown/tests/rolldown/issues/8863/ reproducing the scenario: ESM entry importing two CJS modules + a no-op module with treeshake: false
  • Snapshot verifies require_resource() executes before require_designer()
  • All 1648 existing integration tests pass

## Summary
- When `ensure_lazy_module_initialization_order` transfers CJS init calls to a non-wrapped module, the `PrependRenderedImport` mutations were applied using `prepend()` (`push_front`), which reversed the order of multiple init calls.
- Changed to `append_intro()` (`push_back`) to maintain correct insertion order.

Closes #8863

## Test plan
- Added regression test in `crates/rolldown/tests/rolldown/issues/8863/` reproducing the scenario: ESM entry importing two CJS modules + a no-op module with `treeshake: false`
- Snapshot verifies `require_resource()` executes before `require_designer()`
- All 1648 existing integration tests pass
