DeepSeek Harness Plugin: dsh-ark-quota (Volcano Ark Usage Monitoring)

`dsh-ark-quota` is a plugin for DeepSeek Harness (DSH), designed to enable real-time monitoring of Volcano Ark quotas from the web interface. By reading IAM credentials and calling the OpenAPI, it provides a right-side floating window (supporting multi-tier queries for Coding/Agent Plan), settings-page configuration, and local persistent storage. It supports automatic refresh, keeps AK/SK in local memory for security, and offers a model tool for conversational invocation. Installation requires manually adding the plugin package to `node_modules` and registering it in `cordis.patch.yml`; it takes effect after restarting DSH.
