feat(tui): add 13 preloaded themes matching web design system

Port all web CSS token themes to TUI via shared vocabulary (accent, dim, muted, ok, todo, event, remind, danger). Styles rebuild from active theme on switch. Press T to cycle, persists to ~/.nib/theme. Glamour markdown renderer respects light/dark per theme.
