Retrace star from the Houdini reference; keep the png as a design source

The petal is now a measured bezier teardrop (blunt tip to r~1,
near-straight ~30-degree flare, max width at 60% of the r~14.6
length, rounded dome), matching the original's silhouette at IoU
0.975 against a 1024px render — the residual is the reference's
anti-aliased edge. The center dot is deliberately omitted: the
five-armed star of negative space between the petal tips is the
signature of the design and the dot would fill it.

png/star.png is restored from history as reference/star.png and
tracked: it is a design source (authored in Houdini), not derived
output like the rest of the removed png/ dir.
