… server functions Adds engine-agnostic tests found by mutation testing and by porting external fixture suites while reviewing #8504. Each passes with the current compiler and with the one in #8504. - code splitting: const enums, abstract classes with parameter properties, `using` declarations, non-ASCII text, reference cycles of four declarations, #__NO_SIDE_EFFECTS__ annotations in files with a pragma, side effects kept out of the shared module, the classic React import of a chunk, and shared bindings of loaders in object form or reaching Route through a later-declared helper - route HMR and React Refresh: overloaded lowercase components, method-shorthand component options, split loaders not kept in HMR data - server functions: handlers with type arguments, client references in caller modules, and the missing-handler error Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

🎯 Changes
Test-only. Adds compiler coverage found while checking #8504 (the Babel → Yuku compiler migration): tests for behaviour that mutation testing showed no existing test checks, plus scenarios ported from external fixture suites and old issues. Like #8629, every test passes on
maintoday and on the current #8504 head, so the migration has to keep this behaviour.The tests are engine-agnostic. They call the same compiler entry points on both sides and assert behaviour (what an evaluated module returns, which bindings a module declares or imports, which server functions are extracted) rather than printed output. Most are new rows or cases in the suites #8629 added; no shared helper changes.
