Subject: [PATCH] chore: pick up cadcodec #47 and cadkernel #66; guard the
 re-align length

- acadrust 7ea4247: clamped-knot degree and MINSERT reservation fixes
  (cadcodec #47). cadkernel a0b962a: dogleg fails on a non-finite
  Jacobian (cadkernel #66) and pins the same codec rev, so one acadrust
  stays in the graph.
- The axis re-alignment from #1361 retains its transformed length through
  retain_segment_length, which holds a zero-length segment with per-axis
  differences instead of a P2PDistance whose gradient is NaN there.
