DeepSeek Harness Plugin: dsh-auto-goal-resume

The `dsh-auto-goal-resume` plugin is designed to address the need to manually resume active goals after a DeepSeek Harness (DSH) restart. It enables seamless run continuation by automatically scanning and restoring goals from session logs, and supports cold-restoring agent context. The plugin is idempotent, fault-tolerant, and dependency-free, strictly adhering to round limits and state filtering rules. It is simple to install and activates after restarting DSH, but note the single-instance restriction and potential side-effect risks.
