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.

+# Building From Source
+
+## Prerequisites
+
+- Rust stable
+- Node.js 22
+- npm
+- Git
+
+Platform-specific desktop dependencies:
+
+- Windows: WebView2 runtime
+- Linux: WebKitGTK 4.1, AppIndicator, librsvg, patchelf, pkg-config, and OpenSSL development headers
+- macOS: Xcode Command Line Tools
+
+On Ubuntu 22.04, install the Linux desktop build dependencies with:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y libwebkit2gtk-4.1-dev libappindicator3-dev librsvg2-dev patchelf pkg-config libssl-dev
+```
+
+## Install Frontend Dependencies
+
+```bash
+cd app
+npm ci
+```
+
+## Run Checks
+
+```bash
+cargo check --workspace
+cargo test --workspace
+cargo doc -p dune-manager-core --no-deps
+cd app
+npm run build
+```
+
+## Run In Development
+
+```bash
+cd app
+npm run tauri -- dev
+```
+
+On Linux the app sets `WEBKIT_DISABLE_DMABUF_RENDERER=1` automatically to avoid
+a WebKitGTK 4.1 crash on GNOME Wayland (`Error 71 dispatching to Wayland
+display`). Export the variable yourself with a different value to override.
+
+## Build A Local Production App
+
+For a local production executable without updater signing or release bundling:
+
+```bash
+cd app
+npm run tauri -- build --no-bundle
+```
+
+The executable is written under the workspace `target/release` directory.
+
+## Build Installers
+
+Release packaging is normally handled by GitHub Actions when a version tag is
+pushed. Local full packaging may require platform-specific signing or installer
+setup.
+
+Common local bundle commands:
+
+```bash
+cd app
+npm run tauri -- build --bundles nsis
+npm run tauri -- build --bundles appimage,deb
+npm run tauri -- build --bundles dmg
+```
+
+The app manages already-provisioned servers only. Building from source does not
+add any server setup, provisioning, Hyper-V, or installer workflow to the app.
