dsh-insurance-claim: Auto Insurance Claims Decision

`dsh-insurance-claim` is a model inference plugin based on DeepSeek Harness (DSH), designed to provide pure Node.js logic support for automobile insurance claim decision-making scenarios while avoiding external API dependencies. It enables developers to perform precise calculations and receive deterministic results through parameter inputs, such as loss amounts, running efficiently and stably without network requests. Once installed, the `insurance_claim` tool is loaded automatically and can be invoked directly within a DSH session. The plugin is licensed under the MIT License, and developers should pay attention to code security and ensure that the logic is compliant and standardized.
