Replace "<circular>" with meaningful reference strings using a hybrid approach:
- Objects with names: <EventData-walk>, <BoneData-head>, <Animation-run>
- Objects without names: <TrackEntry-1>, <Bone-2>, <SliderTimeline-3>
Each serialized object now includes "refString" as its first field, enabling
easy navigation from circular references to full object definitions.
- Implement comprehensive C++ serializer generator (tests/generate-cpp-serializer.ts)
- Direct transformation of Java SkeletonSerializer to C++ header-only implementation
- Handle all C++-specific API differences:
* Field access patterns (obj.field → obj->field, private fields → obj->_field)
* Null check removal for reference-returning methods (getBones, getEdges)
* Nested array null check elimination (getVertices, getDrawOrders)
* Enum serialization via switch statements replacing .name() calls
* Custom function replacement system for C++-specific implementations
- Add specialized C++ implementations:
* writeColor: handle public Color fields (r,g,b,a without underscore)
* writeSkin: iterate AttachmentMap::Entries and call writeSkinEntry
* writeSkinEntry: handle AttachmentMap::Entry instead of Java SkinEntry
- Auto-generate both pointer and reference versions of all write methods
- Create JsonWriter.h as header-only port of Java JsonWriter
- Update HeadlessTest.cpp to use generated SkeletonSerializer
- Add comprehensive type analysis and enum mapping from analysis-result.json
- Implement exclusion system for filtering unwanted types/methods
- Fix Java generator nested array null checks that were incorrectly hardcoded
Generated C++ serializer produces identical JSON output to Java reference implementation.
