dsh-crumbs: Short Factual Fills for Long-Running Tasks

`dsh-crumbs` is a plugin for DeepSeek Harness (DSH) designed to address the lack of interface feedback during long-running agent executions. It provides information to human observers by automatically or manually displaying brief, task-relevant facts while the agent is waiting. The plugin supports three modes—autofill, command invocation, and tool invocation—and offers flexible configuration, including customizable display intervals and fact sources (offline pools of verified facts and online-generated unverified content). It is enabled by default and easy to install, and can be activated or configured using environment variables or configuration files.
