dsh-hive: Transforming DeepSeek Harness Sessions into a Peer Collaboration Hive

dsh-hive is a plugin for DeepSeek Harness designed to meet long-term, multi-session, peer-level collaboration needs that the native `subagent` cannot fully satisfy. It transforms top-level sessions into a “hive,” enabling peer-to-peer communication between sessions. Its core features include waking on message delivery, automatic result callbacks, task association, and Send-and-yield (release immediately after sending). Through the `list_sessions` and `send_to_session` tools, users can dispatch tasks and return results across independent sessions, making it suitable for building multi-role collaboration systems.
