features page

• use https://zed.dev/blog/syntax-aware-editing as a starting point for explaining syntax features
  • details should mostly live in :help docs (or entirely but :help docs can't show images yet...)

Not sure we need a lot of marketing, but if we did want to step up our game, then a flashy "features" page with (animated) screenshots (instead of a longish-form embedded video) would go a long way.

(I wouldn't go as fas as the current zed.dev, though; keep it focused on, say, four headline blocks.)
