dsh-omi-voice: Using Doubao Natural Timbre to Read DSH Conversation Replies

dsh-omi-voice is a DeepSeek Harness client plugin that allows users to click the 🔊 icon in a conversation to have the AI's final response read aloud using Doubao TTS natural voice, with support for pause and resume. The speech is synthesized locally by the Omi engine, and the Doubao API Key is stored in the macOS Keychain via a BYOK method, with the plugin communicating only through 127.0.0.1. It is designed for DSH users on macOS who desire an immersive listening experience and are comfortable with character-based billing.
