Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.
Preserves docs/ARCHITECTURE.md.

+
+# Canvas
+
+Use canvas to show HTML on connected Mac/iOS/Android nodes.
+
+## Model
+
+- Canvas host serves files from `plugins.entries.canvas.config.host.root`.
+- Canvas routes live on the Gateway HTTP port (`gateway.port`, default `18789`).
+- Node bridge sends canvas URLs to connected node apps.
+- Node apps render URLs in a WebView.
+- Host name follows `gateway.bind`: loopback local only, LAN IP for LAN, Tailscale host for tailnet, auto picks best route.
+- Localhost URLs only work for a node on the same machine.
+- Paired nodes normally receive node-scoped `pluginSurfaceUrls.canvas` capability URLs; prefer those when available.
+
+## Config
+
+Active config: `$OPENCLAW_CONFIG_PATH` or `~/.openclaw/openclaw.json`.
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "canvas": {
+        "config": {
+          "host": {
+            "enabled": true,
+            "root": "~/.openclaw/canvas",
+            "liveReload": true
+          }
+        }
+      }
+    }
+  },
+  "gateway": { "bind": "auto" }
+}
+```
+
+## Actions
+
+- `present`: show canvas, optional URL.
+- `hide`: hide canvas.
+- `navigate`: open new URL.
+- `eval`: run JavaScript in current canvas.
+- `snapshot`: capture screenshot.
+
+## Workflow
+
+1. Ensure Canvas plugin host is enabled.
+2. Put HTML/CSS/JS under `plugins.entries.canvas.config.host.root` or the default state canvas dir.
+3. Use a route reachable by the target node.
+4. Present the hosted URL: `/__openclaw__/canvas/<file>.html`.
+5. Use `snapshot` when the user needs proof.
+
+## URL shape
+
+```text
+http://<gateway-host>:<gateway.port>/__openclaw__/canvas/index.html
+http://<gateway-host>:<gateway.port>/__openclaw__/canvas/games/snake.html
+```
+
+Path mapping:
+
+- `/__openclaw__/canvas/index.html` -> `<canvas host root>/index.html`
+- `/__openclaw__/canvas/games/snake.html` -> `<canvas host root>/games/snake.html`
+
+## Troubleshooting
+
+- Node sees localhost but is remote: fix `gateway.bind` or public URL, regenerate URL.
+- LAN node cannot load: verify same network, firewall, Gateway port, and auth/capability URL.
+- Tailnet node cannot load: verify Tailscale status and advertised host.
+- Blank page: open URL locally, check browser console, then snapshot node.
+- Live reload missing: verify `liveReload` and file write under root.
