Plugins for DeepSeek Harness (dsh)

Key features

• Plugins for DeepSeek Harness — the "everything is a plugin" agent runtime built on Cordis.
• tools/ — capabilities the model can call
• Tool presentation — whether a session dispatches tools natively, through Code Mode, or both — is chosen once per agent preset and applies to every tool in the session, not per plugin.
• runtime/ — behaviour around the harness, invisible to the model
• ui/ — web client extensions
