KEY FIX: WebKit's GdkWindow receives all pointer events. Connecting
button-press-event on the GtkWindow never fires. Must connect on the
WebKitWebView widget itself (the Wails pattern).
C library now:
- Walks widget tree to find deepest child (WebKitWebView)
- Connects button-press + motion-notify on the WebView
- Does hit-test in C (8px border zone)
- Calls gtk_window_begin_resize_drag with real event data
- Returns TRUE to consume border clicks, FALSE for interior
New: agor-pty/native/agor_resize.c — C shared library that:
- Connects button-press-event on GtkWindow + WebView children in C
- Stores mouseButton, xroot, yroot, dragTime from real GTK events
- Exports agor_resize_start(edge) for Bun FFI
Build: gcc -shared -fPIC -o libagor-resize.so agor_resize.c $(pkg-config --cflags --libs gtk+-3.0)
New: ui-electrobun/src/bun/native-resize.ts — Bun FFI wrapper
App.svelte: simplified to just edge detection + RPC call
