DeepSeek Harness Plugin: dsh-live-model-catalog

This is a DeepSeek Harness (DSH) plugin maintained by CN-WenYu, designed to automatically maintain the model catalog and reasoning tiers for the `llm-pi-ai` route. It syncs new models, capabilities, and reasoning information from endpoints via official APIs, fixes the "Get Available Models" button, is patch-free, supports safe uninstallation, and runs automatically after installation.
