docs(reference): import Dune: Awakening server-manager references

Phase 2 references for the host-agent Dune adapter, moved out of volatile /tmp
into docs/reference-repos/ (per Commander). Three upstream projects, .git +
node_modules + compiled binaries stripped (16MB source). Nested AI-instruction
files (.claude/, CLAUDE.md) removed so they don't pollute Corrosion sessions.

- icehunter/    dune-admin (Go+React) — 4 control planes; SETUP_DOCKER.md is the
                closest analog to our agent's Dune docker control plane (compose
                lifecycle, docker logs, RabbitMQ-via-exec, dune Postgres schema)
- adainrivers/  Rust/Tauri desktop — SSH+k8s BattleGroup control, maintenance
                daemon, in-game admin console (Rust idiom reference)
- the4rchangel/ Node web UI replacing battlegroup.bat — matches the Commander's
                Hyper-V self-host path + game-config schema

See docs/reference-repos/README.md for the full index + how we use each.

+# Bundled service binaries
+
+This directory holds the Linux `dune-server-service` binary (musl-static), its
+systemd unit, and its OpenRC init script. They are populated by the
+`linux-service-binary` job in `.github/workflows/release.yml` and bundled into
+the desktop installer as Tauri resources.
+
+For local debug builds the directory can be empty — the `install_management_service`
+Tauri command surfaces a friendly error when the resource is missing.
+
+For a local end-to-end test, build the service yourself:
+
+```powershell
+rustup target add x86_64-unknown-linux-musl
+cargo install --locked cargo-zigbuild
+cargo zigbuild -p dune-server-service --release --target x86_64-unknown-linux-musl
