wodaimnd/wxmp: Integrate WeChat Official Account article writing, formatting, and draft publishing into DSH

In DSH, the common practice for writing articles for WeChat Official Accounts involves the model generating Markdown, which is then manually copied to the backend for formatting, creating drafts, and publishing. Consequently, the model cannot access the draft box or manage the publishing status. `wodaimnd/wxmp` (package name `@local/wxmp`, category: client, stars: 0) registers the `wxmp` CLI as a model tool named `wxmp`. It provides operations such as `article_new`, `cover`, `draft_create`, and `publish_submit`, along with a three-column workspace interface (Article List / Preview / Publishing Pipeline). Based on the README, this article introduces installation commands, configuration options, a table of complete operation parameters, and fixed return shapes. It also details security defaults, such as `publish_submit` performing a dry-run without the `yes` flag, credential masking, and using `publish_wait` for polling during publishing. Furthermore, it explains that the plugin only registers tools, requires the user to prepare the CLI and WeChat Official Account credentials independently, runs with the permissions of the current DSH process, and advises reviewing the source code and license before use.
