dsh-egg-size: Egg Size Calculator

The `dsh-egg-size` plugin in the DSH (DeepSeek Harness) ecosystem is designed to extend functionality, with a focus on precise “egg size” calculations. It provides an `egg_size` tool that supports parameterized calculations and returns detailed results. It can be installed using the DSH plugin management command `dsh plugin add github:uckkk/dsh-egg-size`. Implemented in pure Node.js, the plugin requires no network access and is suitable for offline or restricted environments. As it is released under the MIT open-source license, it is recommended to review the source code before installation. Once installed, the tool can be invoked within a DSH session.
