Explain failed DeepSeek Harness agent runs locally

Key features

• Turn a failed DeepSeek Harness run into a redacted recovery plan in seconds.
• After a failed run, use /postmortem
• Commands use recordInputfalse: selecting a historical turn does not enter the session event log.
• This is a failure-explanation and recovery-planning plugin for DSH users who need a safe next action after an agent run fails.
• Local-first, read-only, and useful without a model.
