WeCom AI Bot channel for DeepSeek Harness

Key features

• One conversation = one agent — mounts a preset (default standard) in its scoped setup, so it has the preset's tools (bash, read, edit, skills, …) and persona.
• Status service — ctx.get('wecomChannelStatus').snapshot() returns plain scalars (connected, stopping, conversations, authenticatedAt, lastError) for dashboards and UI plugins.
• Session ids are derived deterministically (sha256(namespace · scope · peer), no raw userid) and survive restarts via sessionPersistence.
• Media support — images are downloaded, decrypted with the official SDK, and attached when the model can view them
• files and videos land in the agent's workspace for its tools.
