DeepSeek Harness Plugin: jwilson411/dsh-tool-quota

The DSH (DeepSeek Harness) plugin `dsh-tool-quota` is used to restrict an agent's tool calls. Through a configuration file (supporting specific tools or the wildcard `*`), it enforces limits on the number of tool calls and the byte size of returned results within each session. When a limit is reached, the plugin throws an explicit error instead of performing silent truncation. It also provides a `tool_quota_status` tool for the agent to query remaining quotas, helping prevent context bloat and resource waste.
