CDSL Bridge: Standard Hole Wizard

Choose the hole subtype from function: clearance, blind, through, counterbore, countersink, or threaded intent.
Use hole_wizard only with its exact schema fields and a resolvable host face, or use a self-contained circular cut when the frame is explicit.
Positions are objects such as {"mm": [u, v, w]}; never emit bare coordinate arrays.
Thread metadata is retained as intent but current geometry is cylindrical; report the approximation.
