dsh-picky-eat: Picky Eating Correction Plugin

The DeepSeek Harness (DSH) plugin `dsh-picky-eat`, maintained by uckkk, focuses on "picky-eater correction." It returns behavior correction suggestions based on parameters. Implemented in pure Node.js with no network dependencies, it can be installed with the command `dsh plugin add github:uckkk/dsh-picky-eat` and requires the `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` dependencies. Once enabled, its tools can be invoked directly within the session.
