DeepSeek Harness Plugin: dsh-word-complete

`dsh-word-complete` is an intelligent word auto-completion plugin for the DeepSeek Harness Web environment. It uses the current session history to track word frequency and provides completion suggestions without requiring external dictionaries. The plugin supports keyboard and mouse interaction, sorts suggestions by match quality and word frequency, and includes a cursor-following feature. In terms of implementation, the Host side handles statistics, while the Client side handles UI rendering. The plugin is available under the MIT license, supports installation and updates via CLI, and aims to improve the efficiency of developers entering specific terms in long conversations.
