Subject: [PATCH] fix(electrobun): use window.resizeTo/moveTo for resize
 (proven in Chromium)

Replaced entire FFI chain (XMoveResizeWindow, begin_resize_drag,
XUngrabPointer) with standard browser APIs window.resizeTo + window.moveTo.

Proven to work in Chromium --app mode with same JS resize logic.
Frame captured synchronously via window.screenX/Y + outerWidth/Height.
Zero RPC, zero FFI, zero GTK involvement.
