Align aerospace keybindings with i3+sway and add resize mode

- Enable programs.aerospace to ensure config generation
- Disable normalizations for pure i3-style tree management
- Update layout keybindings to match i3+sway:
  - cmd-w: accordion-horizontal (tabbed)
  - cmd-s: accordion-vertical (stacking)
  - cmd-e: tiles layout with orientation toggle
- Replace direct resize bindings with cmd-r resize mode
- Add resize mode with hjkl directional controls
