dsh-cybernetics: DeepSeek Harness Cybernetic Core

The Cordis plugin for DeepSeek Harness (DSH), based on engineering cybernetics mechanisms, provides agents with dynamic stability regulation analogous to physical systems. It employs observer, feedforward, and feedback control loops to enable state persistence, tool interception, and dynamic gear adaptation, thereby ensuring system stability. For installation, symlink the host's `node_modules` to the plugin directory and avoid running `pnpm install` directly. The configuration file controls EMA filtering, gear thresholds, and oscillation detection. During development and debugging, watch for HMR side effects, integrator saturation in the stability valve, and parameter field name changes; restarting `dsh web` is recommended to ensure changes take effect.
