feat(warpd): rewrite config for v2.2.0 with Colemak nuei layout

Update warpd home-manager config to target atuan26/warpd v2.2.0:
- Movement: nuei (left/down/up/right) for Colemak home row
- Scroll: capitalised movement counterparts (M/J/T/R)
- Grid: navigation mirrors movement keys; quadrant selection on q/w/a/r
- Add v2.2.0 options: smart_hint, screen_chars, grid cut keys, indicator
- Fix acceleration (1 → 700), add max_speed/decelerator_speed
