Continue the five-dimensional kissing-number campaign on https://github.com/wustep/maths from current main. Folder problems/kissing-5d/compute/q2/.

Published range still 40 ≤ τ₅ ≤ 44. Hunt: an exact dual excluding some k in {41,42,43} with no restricted angle set, or a new exact 41-point code in S⁴. Do not claim τ₅ = 40.
