dsh-jev-thinking: Automatically Determine Thinking Depth for Prompts

The `dsh-jev-thinking` plugin is designed to automatically set an appropriate `reasoningEffort` parameter for DeepSeek Harness (DSH) agents. It determines the reasoning intensity by querying the Jev model and is licensed under the MIT License. Core features include reading routing options, single-turn prompting, and context completion that incorporates the previous response. After installation, a TypeSafe API Key must be configured, with a default timeout of 2500 ms. When using it, note limitations such as context dependency, relatively high token consumption, potential increased costs due to routing support, and the absence of a fallback strategy.
