dsh-telegram-channel: Attach Telegram to Local DSH Web Sessions

dsh-telegram-channel is an MIT-licensed plugin maintained by hi-wenw, designed to provide remote control functionality for DeepSeek Harness (DSH) via the Telegram mobile app. It attaches to a locally running `dsh web` session, enabling synchronized trajectory and bidirectional visibility between the mobile device and the computer's web interface. This solves the inconvenience of viewing context or sending supplementary commands when away from the computer. The tool supports executing commands via a Telegram Bot, including `/sessions` to attach sessions, `/last` to view history, `/model` to switch models, and `/unbind` to disconnect bindings. Installation requires Node.js >=22 and a Bot Token, and it is compatible with Windows, macOS, and Linux.
