beta.22: manual cookie join, anthropic-client-platform header, ephemeral session, expose usage 403 body

didFinish only fires for cross-document (full page) navigations. After
loading https://claude.ai/login the SPA redirects authenticated users
via history.pushState to /new — this changes the URL visually but never
fires didFinish, so auth was never detected.

KVO on webView.url fires for every URL change including SPA pushState,
covering the case where the app routes client-side after the initial
page load. Both KVO and didFinish now call the same checkCurrentURL
helper so detection is not missed regardless of navigation type.

-## What's new in v1.1.4-beta.2
+## What's new in v1.2.1-beta.18
 
-### Improvements
-- Plan name (e.g. Pro, Max) is now read from the API instead of being hardcoded
+### Bug fixes
+- Replaced callAsyncJavaScript fetch approach with WebKit navigation: instead of running `fetch()` in the page's JS context (which was returning 401 because it bypasses the SPA's auth interceptors), each API call now navigates the WebView to the API URL directly. WebKit sends full browser headers and cookies automatically at the HTTP layer, the same way a real browser navigation works. This is more reliable regardless of what server-side auth mechanism claude.ai uses.
+- API calls are now sequential to share a single WebView for all navigations
+- Added redirect detection: if WebKit follows a 302 to /login, the response is treated as an auth failure rather than returning HTML to the JSON parser
+
+## What's new in v1.2.1-beta.17
+
+### Bug fixes
+- Fixed "Not signed in" after login by adopting the login WebView directly for API calls
+- Added diagnostic error messages for JS errors and unexpected responses
+
+## What's new in v1.2.1
+
+### Bug fixes
+- Fixed WebKit suspending the background WKWebView: anchored in a transparent 1×1 NSWindow
+- Fixed login window auto-closing before sign-in completes
+- Added /api/organizations as a final fallback for org ID resolution
+- Fixed Settings incorrectly showing "Signed in" after a failed refresh
