DSH Remote Control: Enabling Agents to Control Local DSH Instances

The `dsh-remote-control` plugin allows an Agent to directly control another independent DSH instance in a zero-intrusion manner, addressing the limitations of collaboration within a single instance. Its core capabilities include direct control of remote sessions, incremental reads, search, and reference management, and it provides six persistent tools, such as session creation and message sending. After installation, connection information must be configured in the conversation, enabling the Agent to use the plugin for testing, collaboration, and decomposing complex tasks.
