Pull request overview

This PR advances the extension to the next plugin version by replacing the inworld object explorer TreeDataProvider with a custom webview-based explorer UI, adding workspace-local pin/restore for published objects, and introducing a generalized RPC command interface plus staged (pre-generated) language definition artifacts.

Changes:

• Replaced the inworld explorer tree view with a custom webview UI (filtering, context menus, inline create/rename, run/stop, permission icons, pin/unpin, offline pinned view).
• Added workspace-local pinned-object persistence and reconnect restoration, plus “save back to contents” support via viewer commands.
• Switched language definition consumption toward staged artifacts + autobuild-based syncing/validation, and introduced a generic command.execute / command.list RPC surface.

src/webview/explorer/explorer.ts:554

• Unescaped linked-prim metadata is inserted into the title attribute. Because this is HTML built via innerHTML, a linked prim name/description containing quotes can inject markup into the webview. Escape the title string first.
  src/webview/explorer/explorer.ts:585
• Unescaped item metadata is embedded into the title attribute (label/description). Since the tree is rendered via innerHTML, a malicious description containing quotes/markup could lead to webview XSS. Escape the computed title string.
