fix: use requestAnimationFrame before fit() on window resize

When window resize fires, CSS layout hasn't settled yet. Adding
requestAnimationFrame ensures the browser has calculated new sizes
before xterm.js fit() reads the container dimensions. Reduced
debounce from 250ms to 100ms since rAF handles the layout timing.
