Feature Gap Analysis: ArkavoCreator vs Warudo

Summary

This issue documents a comprehensive feature comparison between Warudo (the leading 3D VTubing software) and ArkavoCreator to identify gaps and prioritize development efforts.

Warudo represents the current industry standard for 3D VTuber streaming with extensive motion capture support, streaming platform integrations, and a visual scripting system. This analysis helps inform ArkavoCreator's roadmap to achieve feature parity where appropriate while leveraging our unique strengths (native Apple/Metal performance, privacy-first architecture, local LLM integration).
