Motus.NET 0.17.0

Added

• TransferSegment and MotionProgramRequest.TransferPlannerFactory: inject RRT-Connect for joint-space travel between Cartesian hover poses while keeping precise LIN approaches/retracts.
• PickPlaceOptions with opt-in sampling transfers and explicit gripper TouchBodies; segment-local AllowedCollisionPairs keep all other objects checked.
• Trajectory.AttachSpans carries attachment geometry, source names, TCP-local poses and release poses through retiming and JSON/CSV export.
• Multi-object pick/place and carried-object obstacle-routing regressions; all four retimers checked for dwell/event/export consistency.

Fixed

• Pick/place opens and detaches at placement before retraction; released workpieces remain in the collision scene.
• Motion programs honor the supplied robot-only checker and serial chain, validate attach/detach transitions, reject duplicate/missing attachments, and check tool-state warnings against each segment's scene.
• Retiming preserves SET/WAIT durations and stops at program/attachment boundaries. Export retimes once with the selected algorithm; CSV uses invariant numbers and escaped JSON cells.
• Mesh detach restores geometry at its release pose; attachment lookup is case-insensitive.

Changed

• Development package/version files and Grasshopper pin aligned to 0.17.0.
