dsh-liketavern: SillyTavern-Style Role-Playing in DeepSeek Harness

`dsh-liketavern` is a plugin for DeepSeek Harness that introduces a SillyTavern-style interface to dsh, addressing the native interface's limitations in state management for complex roleplay. It supports importing multi-version character cards, three-tier world books, BM25-based intelligent memory, and story branching with lossless rollback. Through a sandbox and the EJS engine, it ensures safety and flexibility, making it suitable for scenarios requiring deep narrative creation and state management.
