WebKit usage

CodexBar uses WebKit in two places:

• Visible login/purchase windows (e.g. Cursor login, credits purchase).
• Offscreen WebViews for OpenAI dashboard scraping.

Teardown helper

Use WebKitTeardown whenever a WKWebView + NSWindow should be torn down or hidden. It centralizes Intel-friendly cleanup:

• Stops loading and clears delegates.
• Delays teardown so WebKit can unwind callbacks.
• Keeps owners retained briefly on x86_64 to avoid autorelease crashes.

When to use

• Any WebKit window that closes after a flow (login, purchase, etc.).
• Offscreen WebView hosts that hide/close after scraping.

Notes

• For login flows that persist cookies manually, prefer WKWebsiteDataStore.nonPersistent().
• Keep window isReleasedWhenClosed = false when teardown is deferred.
• Avoid closing WebViews directly; route cleanup through the helper.
