dsh-model-context-catalog: Maintaining the Context Window for llm-pi-ai

The dsh-model-context-catalog plugin, maintained by HOWILLMAKEIT, addresses false-positive overflow issues in DeepSeek Harness (DSH) for llm-pi-ai models caused by an excessively small default context window of 262,144 tokens. By maintaining accurate route-level contextWindow values and correcting metadata, it prevents tool-calling failures. It provides a web management interface that allows users to configure the actual context windows for different provider/model routes. After installation, users need to add and save the model in settings, ensuring that the plugin runs the model according to its true capacity.
