dsh-session-assistant: Full-Duplex Voice Assistant for the Current Session

**dsh-session-assistant** is a full-duplex voice assistant product layer for DeepSeek Harness Session. It provides voice discussion, draft maintenance, and secure submission features, supporting real-time full-duplex conversations with an agent and optional knowledge organization. This plugin depends on `dsh-multi-model-provider` and `dsh-realtime-voice`, and requires manual installation and adaptation to specific versions. Its core value lies in leveraging browser-based speech recognition capabilities to lower the barrier to using voice-interactive agents while ensuring the security of data and audio.
