ISEKAI-BE

Maintain the ISEKAI-BE backend repository. Use when Codex needs to implement or review backend changes, fix bugs, update configuration, adjust WebSocket or Gemini flows, modify character/chat/member/storage/security domains, run repository validation, or explain this Kotlin/Spring Boot codebase.

Update this repository's README so it matches the current implemented scope. Use when the user asks to create, rewrite, or refresh README content, document new features, update setup or deployment instructions, or keep the README in sync with current code, configuration, Docker deployment, Raspberry Pi behavior, or project limitations.
