dsh-cook-time: Blanching Time Schedule

The DeepSeek Harness plugin `dsh-cook-time` is designed to address local gathering time-planning scenarios, following the core design principle of “everything is a plugin.” Implemented purely in Node.js, it requires no network requests and only needs to receive parameters to return a hot pot dinner plan. Developers can install it via a command and directly invoke the `cook_time` tool in a session to obtain the result. It is suitable for scenarios requiring rapid generation of local logic, runs with the current process permissions, and the MIT license should be consulted.
