The main process was resetting webContents zoom to 1 on every
\zoom-changed\ event, which fires not just for native Chromium zoom
gestures but also for the renderer's own setZoomFactor IPC calls. Paired
with a keydown listener that re-sent the current zoom on every
ctrl-combination (ctrl+backspace, ctrl+z, ctrl+v, ...), this created a
self-triggered race that intermittently snapped the factor back to 1.
Make the renderer the single source of zoom truth: keyboard, wheel, and
menu all drive the same Solid signal, preventDefault blocks Chromium's
built-in accelerators before they race, and the main process disables
pinch zoom and no longer listens to zoom-changed.
