Peter SteinbergerandGitHub b363d5a293 feat(linux): canvas UI via CLI-node + Tauri app IPC bridge (#107633 )

* feat(linux): canvas via CLI-node + Tauri app IPC bridge

* refactor: extract gateway helper modules

* build(linux-canvas): register plugin package in lockfile

* fix(linux-canvas): move canvas advertise test out of core, regen docs/protocol/deadcode

* fix(gateway): break node-catalog/registry import cycle via leaf normalize module; add canvas glossary term

* style: oxfmt invoke.ts and runtime.ts after buildNodeEventParams extraction

* fix(linux): load Canvas WebView via dedicated data_directory context

Wry's Linux/WebKitGTK incognito mode discards Tauri's registered
WebContext (wry webkitgtk/mod.rs), so the Canvas window got a fresh
ephemeral context without the openclaw-canvas:// scheme handler — the
bundled A2UI page never committed (stayed about:blank) and every A2UI
command timed out. Use an isolated cache-backed data_directory instead,
which keeps the protocol handler while still isolating Canvas storage
from the dashboard window.

* fix(linux): keep Canvas WebView ephemeral via incognito + data_directory

Autoreview flagged that a dedicated data_directory alone persists Canvas
browser state (cookies, localStorage, IndexedDB, service workers) across
restarts, so an agent that navigates Canvas to a site could leak an
authenticated session into a later session. iOS uses a non-persistent
store; Linux should match.

Add .incognito(true) alongside .data_directory(): the distinct directory
gives Tauri a fresh WebContext key so it still attaches the
openclaw-canvas:// protocol closure, and incognito makes Wry swap in a
fresh *ephemeral* context carrying those protocols. Live-verified on a
Wayland/WebKitGTK box: the bundled page still loads
(location.href=openclaw-canvas://localhost/index.html, openclawA2UI
present, A2UI renders) and the canvas-webview dir holds no persistent
cookie/storage files.
