@dingyi222666/dsh-wakatime: WakaTime Plugin for DeepSeek Harness

`@dingyi222666/dsh-wakatime` is a WakaTime plugin specifically developed for DeepSeek Harness (dsh), designed to track AI coding activities, lines of code, and time spent. Licensed under the MIT license, this plugin supports profiles that run agent loops, such as `web`, `headless`, and `tui`, and requires dsh version 0.1.2-alpha.5 or later. Core features include automatically managing the `wakatime-cli` download, detailed tracking of various file editing operations, calculating AI code change metrics, implementing a heartbeat rate limit of once per minute per project, and automatically flushing pending data upon session end. The plugin is designed with zero runtime dependencies, utilizing only built-in Node.js modules.
