dsh-session-relay: Organizing multiple DSH root sessions into a handoff-capable collaboration team

dsh-session-relay is maintained by SunsetRNE under the MIT license; the current version is 2.0.0 and it falls under the SkillHub workflow category (0 stars). Instead of wrapping DSH sub-agents, it groups multiple peer root sessions into a set: one main session coordinates while the other working sessions carry their own context, reporting via `peer_report` and performing batch merging to wake up. The README provides the `/relay` command, 14 `peer_*` model tools, a read-only task board exported from `.agents/TASKS.md`, backlog queue backpressure, collaboration tags in the right sidebar, instruction templates, full-text search, as well as read-only integrations for GitHub issue projection, Projects Status, and task PRs (disabled by default). It requires DSH 0.2.2-rc.1 or higher to run and can be installed via the DSHA plugin manager from GitHub Releases, repository links, or local tarballs. All GitHub write operations are handled on the user command side, leaving no write access for the model.
