cad: v0.4.0

0.4.0 (2026-10-31)

⚠ BREAKING CHANGES

• cad: check minimum walls per process and limit block_like to solid parts
• cad: the pair cache moves to hw/.cad/pairs-v2.sqlite; a sweep whose between-sample check leaves an interval unproved now reports status "incomplete" and exits 2 (use --no-continuous for a sampled-only run); sweep run records live under hw/.cad/runs/; timings_s counters are renamed (kernel_evaluations, exact_hits, ...).
• cad: catch missing retention and see-through FDM parts at L2
