dsh-sticker-hub: A local sticker library for DSH

dsh-sticker-hub is a DSH plugin maintained by lukcyspring that converts stickers into a local, taggable, semantically searchable, and directly sendable resource library. The plugin comes without images or API keys; the sticker library is populated by pulling from upstream or by manually placing files into the `gallery` directory, while image recognition uses any OpenAI-compatible endpoint. It offers six tools: `sticker_search`, `send`, `learn`, `battle`, `stats`, and `show`. It supports playing "Sticker Battles" in IM channels like QQ (where only images are replied to, without text) and supports inline display in GUI chat windows as well as `[sticker:name]` tags in message bodies. This article organizes installation commands, the process of pulling libraries and tagging images, and common configuration items based on information verified in the README, and explains the boundaries between the MIT license for the code and the licenses of the upstream image sources.
