A self-evolving plugin for DeepSeek Harness (dsh)

Key features

• The mutation vocabulary is code, the content is model-generated.
• The LLM never invents asset kinds or operators
• it only fills in payloads that pass the closed zod schema.
• Validation is by execution, not by self-claim.
• A proposal is applied only when a sandboxed trial beats the baseline on observable metrics.
