Sample a straight-line path in joint space from from to to over steps
segments, yielding steps + 1 samples (inclusive of both endpoints). Each
sample carries the interpolated per-DOF values (clamped to range) and the
forward-kinematics poses of every node. Joints absent from from/to hold
their stored value at both ends.
