dsh-feishu-bridge: Driving a Local DeepSeek Harness Agent with Feishu Messages

`dsh-feishu-bridge` is a plugin that connects Feishu with a local DeepSeek Harness. It allows users to send messages in a Feishu direct chat to remotely drive a local Agent to execute tasks. This solution does not require a public IP, uses long-lived connections to handle events, and supports message-driven workflows, security validation, and management commands. Installation requires Node.js >= 22 and DSH >= 0.1.0-rc.6, with the `appId`, allowlist, and permissions configured via environment variables. High-risk tools are disabled by default. Currently, only plain text in direct chats is supported, and sessions are not restored after a restart, making it suitable for scenarios where mobile or remote users need to quickly trigger local computations.
