fix(electrobun): disable all GTK FFI, JS-only resize via setFrame RPC

Browse source 
Bun segfaults (address 0x10) from prior GTK widget tree modifications
(wrapWebViewInScrolledWindow corrupted the tree). Disabled all GTK FFI
except begin_move_drag (which works). JS handles capture mouse events,
compute delta, and call window.setFrame RPC.

Clean build required: rm -rf ui-electrobun/build/

Status: resize outward works, resize inward blocked by WebView min-size.
Next: need C shared library for proper GTK signal connection.
