dsh-narrative-voice: DeepSeek Harness Request-Tool Pronoun Consistency Plugin

`dsh-narrative-voice` is a DeepSeek Harness (DSH) plugin designed to address pronoun inconsistency caused by perspective drift in the `ask_user_question` tool. During prompt construction, it rewrites tool descriptions to enforce a consistent referent for “I” and “you,” ensuring clear interaction. It supports two modes—“AI narrative” and “user narrative”—and can be switched in real time via the `/voice` command. The plugin has no dependencies; after installation, it takes effect after restarting the process. It is mainly suitable for application scenarios that require high consistency in interaction perspective.
