ux: dashboard-style startup — fullscreen Startify, m1ngsama header

- Remove NERDTree auto-open on bare `vim` — Startify now renders
  fullscreen like neovim's snacks dashboard (use Ctrl+n for tree)
- `vim .` keeps NERDTree left + Startify right (directory workflow)
- Replace minimal text header with centered m1ngsama ASCII block art
  (mirrors neovim config aesthetic)
- Center art and info subheader dynamically based on window width
- Add startify_padding_left = 4 for list item breathing room
- Reorder lists: Sessions → Recent Files → Current Dir → Bookmarks
