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.
