beta.18: navigate-and-read API fetch replaces callAsyncJavaScript

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 v1.1.3
+## What's new in v1.2.1-beta.18
 
-### UI polish
-- Limit headers now read "5 Hour Limit" and "7 Day Limit"
-- Tapping anywhere on the blue update banner opens the update window
+### 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
 
-### Session Diary fix
-- Burn history is persisted across app launches — the sparkline populates immediately on first open instead of requiring a manual refresh
+## What's new in v1.2.1-beta.17
 
-### Window sizing fixes
-- The popover now resizes correctly when switching between the main view and settings
-- Background colour no longer shows through during the resize animation
+### 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

+  "notes": "## What's new in v1.2.1-beta.17\n\n### Bug fixes\n- Fixed \"Not signed in\" after login by adopting the login WebView directly for API calls — the login WebView is proven-authenticated (user just completed sign-in in it), so reusing it eliminates the problem where a separately-loaded background WebView might not have the full auth context (localStorage tokens, Service Worker state) that claude.ai requires\n- Added diagnostic error messages: JS errors, WebView URL, and unexpected response types are now surfaced in the error banner to aid future debugging\n\n## What's new in v1.2.1\n\n### Bug fixes\n- Fixed the root cause of \"Not signed in\" after being clearly signed in: claude.ai's auth requires credentials beyond plain HTTP cookies (localStorage tokens, Service Worker state, etc.) that URLSession cannot access. All API calls now run via callAsyncJavaScript inside a background WKWebView, using the same fetch path the page itself uses — credentials are included automatically.\n- Fixed WebKit suspending the background WKWebView: a WKWebView with no window is throttled/suspended by macOS, preventing JS execution. The background WebView is now anchored in a transparent 1×1 NSWindow, keeping it active.\n- Fixed login window auto-closing before sign-in completes — login window loads `/login` and only detects auth when back on claude.ai (not on OAuth provider redirects)\n- Added `/api/organizations` as a final fallback for org ID resolution\n- Fixed Settings incorrectly showing \"Signed in\" after a failed refresh"

-# ClaudeChecker for Windows
-
-A native Windows port of ClaudeChecker — a system tray app for monitoring your Claude AI usage limits in real time.
-
-## Requirements
-
-- Windows 10 / 11 (x64)
-- [.NET 8 Runtime](https://dotnet.microsoft.com/download/dotnet/8.0)
-- [WebView2 Runtime](https://developer.microsoft.com/microsoft-edge/webview2/) (usually pre-installed on Windows 11)
-
-## Building
-
-```powershell
-cd windows
-dotnet build -c Release
-```
-
-The output is a single `ClaudeChecker.exe` in `bin\Release\net8.0-windows\`.
-
-> **Assets:** You need to supply `Assets/icon.ico` and `Assets/icon.png` (128×128) before building.
-> Copy them from the macOS project's `ClaudeChecker/Assets.xcassets/AppIcon.appiconset/`.
-
-## Features
-
-- System tray icon — left-click to show/hide the popup
-- 5-hour and 7-day usage gauges with burn rate sparklines
-- Cookie-based auth via embedded WebView2 browser (sign in once, session persists)
-- Auto-refresh on a configurable interval (1–10 min)
-- Update checking against the same `version.json` / `version-beta.json` as the macOS app
-- Beta channel toggle
-- Settings panel (auth, refresh interval, update channel)
-
-## Architecture
-
-| File | Purpose |
-|---|---|
-| `App.xaml.cs` | Tray icon, popup lifecycle, refresh timer |
-| `PopupWindow.xaml/cs` | Main UI — limit cards, settings, update sheet |
-| `LoginWindow.xaml/cs` | WebView2 browser for claude.ai auth |
-| `UsageViewModel.cs` | Data fetching, cookie handling, state |
-| `UpdateManager.cs` | Version checking, download and install |
-| `Models.cs` | Data models |
-| `Controls/GaugeControl.cs` | Custom circular gauge |
-| `Controls/SparklineControl.cs` | Burn history sparkline |
-
-## Notes
-
-- Cookies are stored in user settings (via `Properties.Settings`), not the WebView2 profile, so they survive WebView2 cache clears.
-- Updates download a `.zip`, extract, and run a `.bat` script that replaces the exe after the app exits.
-- The popup positions itself in the bottom-right corner near the system tray.

-## What's new in beta.36
-
-### Bug fixes
-- Settings no longer incorrectly shows "Not signed in" when limits are working
-- Session Diary now shows correctly after the first successful refresh
-- Extra Usage Credits section now restored from cache on startup
-- Plan name, overage, and prepaid credits are now cached and shown immediately on launch
-- App now loads cached state instantly on startup before the background refresh completes
