Rebuild three hulls from the pre-refactor sprites

The Psych Bike is untouched.

I had been working from public/classes.js, which is the 2025 refactor. The
actual originals are in public/sketch.js before commit 67f8168, and they are
markedly richer -- the refactor had flattened them.

Superbug. The 2025 version is two circles and a fin. The original also has a
pair of orange quads swept up and outward with four yellow struts running
over each, the longest reaching from the shoulder at (+-9.6, -9.6) out to
(+-19.2, -19.2). Those are the antennae, and they are most of why the craft
reads as an insect rather than a pod. Reproduced at the original
coordinates, with lit tips so the diagonals end in something.

The Compiler. The original already had the bones of an Imperial ship: a wide
horizontal fuselage bar spanning +-1.16 wid with green rails, bracket wings
rooted at +-0.5 and bowing to +-1.4, and swept nose fins. Only the nose was
wrong -- it was a dome. That becomes a long triangular prow with panel lines
and a bridge tower at the stern, and the rest of the original structure
carries over unchanged. The wide bar is also the thing that made this craft
cohere; I had been inventing pylons to do a job the original already did.

Voidwalker. The original is a 15x12 pixel sprite -- 54 hull cells and 24
accent cells forming a spine with stepped wings and outboard slabs -- not
the three plain columns the refactor reduced it to. Decoded cell for cell
and rendered as chamfered plates that overlap slightly, so the layout stays
blocky while the surface reads smooth.

Accents are held back deliberately. At full brightness the 24 white cells
take the craft over and it reads as a white ship with purple trim.
