Electron Releases

The <webview> guest-inheritance list clamps a guest to be no less restricted than its embedder for nodeIntegration, contextIsolation, sandbox, and friends, but nodeIntegrationInWorker was missing — so a webpreferences="nodeIntegrationInWorker=1" attribute was honoured even when the embedder had it off. nodeIntegrationInWorker was also absent from getLastWebPreferences(), so the inheritance check had nothing to compare against.

• Add nodeIntegrationInWorker to the inherited web preferences for <webview> (and the equivalent window.open list).
• Emit nodeIntegrationInWorker from SaveLastPreferences() so it round-trips through getLastWebPreferences(), matching nodeIntegration.
• Document the <webview> inheritance behaviour; add regression coverage.

Notes: <webview> and window.open now inherit nodeIntegrationInWorker from the embedder, consistent with the other Node and sandbox preferences.
