Clavyn v0.1.2-alpha.5

What's Changed

Tab drag-and-drop now works in the shipped desktop app, not just in the test harness. Tauri's dragDropEnabled window flag defaults to true, which installs a native drag-drop handler on the webview that swallows every drag before it reaches the DOM — dragstart/dragend fired, but dragenter/dragover/drop never did, leaving the split, swap, and reorder handlers from alpha.4 as unreachable dead code. The app registers no tauri://drag-drop listeners, so disabling the flag removes nothing and fixes the issue on WKWebView, WebView2, and WebKitGTK alike. (#34)

Also included: a new native-e2e agent skill documenting how to test and debug features that cross the webview↔OS boundary (drag-and-drop, clipboard, dialogs, windowing) in the real packaged app on macOS, Linux, and Windows. (#34)
