dsh-loom: Run auditable RSI workflows in sub-sessions when the main agent is idle

dsh-loom is a workflow plugin released by DarknessLED for DeepSeek Harness. It executes a recursive self-improvement chain—consisting of reconnaissance, multi-candidate generation, mechanical verification, scoring, and promotion—in sub-sessions, while keeping the main agent idle and only waking it at checkpoints. Campaign state and costs are written to an append-only event log. It provides tools such as rsi_start, rsi_control, rsi_decide, rsi_doctor, and a sidebar RSI panel. The installation command is `dsh plugin --profile desktop add DarknessLED/dsh-loom`. The default data directory is `~/.dsh/loom/`, and it requires dsh >=0.2.0-rc.2 and Node ^22.19.
