"Make connection" checkbox in the Fit dialog moves/orients the other board so
its tenon seats into the mortise (faces meet, insertion axes aligned, cross-axes
matched):
- scene.connect(anchor, moving): builds the moving feature's desired world frame
from Part.feature_world_frame, solves R = [dN|dU|dV]·[n|u|v]^T, decomposes to
yaw/tilt/roll via matrix_to_ypr (inverse of local_frame's Rz·Ry(-tilt)·Rx(roll)),
and positions so the contact points coincide. Verified: tenon-board stands and
seats into a top mortise; Euler round-trip exact.
- Feature.rotation_deg: spin a feature about its face normal (geometry rotates
the cut/add solid; preview + connect honor it) so cross-sections line up.
- Shared face_frame/rotation math moved to scene.py (geometry imports it).
- CLI `connect`, `--rotation` on features; voice `wood-connect`; GUI rotation
field + "Make connection" checkbox. 22 wood-* tools.
79 tests pass (ypr round-trip, connect seats tenon, rotated feature cuts).
