DeepSeek Harness Plugin: dsh-wechat-collector

`dsh-wechat-collector` is a WeChat Official Account collection plugin designed specifically for DSH, aimed at simplifying the full workflow from article collection and author analysis to import into ContentStudio. The plugin uses a local runtime (based on `uv`) to handle interactions with WeChat, supporting QR code login, account management, crawl control, and automatic handling of rate limits. In terms of features, it provides a rich set of DSH tools, including runtime management, account login and crawl control, RSS external source supplementation, content preview, manual feedback write-back, DeepSeek creator analysis, and idempotent import into ContentStudio. The plugin emphasizes security: credentials are stored only in named configuration files and do not enter the DSH main process. System requirements include Node.js 22.19.0+; currently, the first run starts the main process.
