Replace the Grok braille logo with a procedurally generated moon

Browse Source 
The welcome logo (hero box, stacked layout, and minimal's welcome card) is
now a braille moon that waxes and wanes through a full 8s lunation,
echoing the Kimi CLI's moon-phase spinner. The disc is rasterized into the
2x4 braille dot grid at render time — round at any size, no art assets —
with the terminator at x = cos(2*pi*p)*sqrt(1-y^2) and a faint outline
ring so the silhouette survives new moon. The full moon grows to 20x10
cells (from the 14x7 slashed-circle art) and the small tier to 10x5; the
old logo*.txt assets are deleted. Geometry is unit-tested (wax/wane
monotonicity, quarter-phase symmetry, right-limb-first waxing, silhouette
at new moon, round raster).
