dsh-blame-avoid: Introducing the Blame-Avoidance Plugin

`dsh-blame-avoid` is a lightweight, network-independent DeepSeek Harness (DSH) plugin designed to simplify development workflows. It provides a “blame avoidance” tool that returns specific structured results based on parameters. The plugin is maintained by user `uckkk` and requires the dependencies `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6). Users can install it via a command and invoke the tool directly in a session to handle parameter differences and return structured data.
