Plugin to make dsh compatible with SillyTavern artifacts

Key features

• V1/V2/V3 JSON and PNG character cards (can be created, edited after importing, and exported to the current JSON/PNG)
• One plug-in, unified loaderformat parsing, resource management and DSH runtime layering, but only one root plug-in is installed, which does not cause version and loading order issues between multiple plug-ins.
• Chinese User GuideModule-by-module operations, data and compatibility boundaries
• No independent account authentication: /dsh-tavern/api/ uses real TCP peer, Host, Origin and Content-Type protection, but local trusted processes may still access it.
• Independent world books, character card-embedded world books and user-bound world books
