- Replace static imports of deprecated ComfyButton and ComfyButtonGroup with dynamic imports
- Only loads legacy API files when frontend version < 1.33.9 (backward compatibility path)
- Frontend >= 1.33.9 users no longer see deprecation warnings since legacy code is never loaded
- Preserves full backward compatibility for older ComfyUI frontend versions
- All existing tests pass (159 JS + 65 Vue tests)
