Cad Khana
Diagnostics-first CAD wrapper around Build123d: assembly-level interference/clearance assertions plus optional per-part printability checks. Load BEFORE editing an `assembly.py` that uses the wrapper or interpreting its diagnostic JSON — SKILL.md has conventions the scripts rely on but don't restate. TRIGGER: about to run `khana check`/`build`/`view`/`draw`, or editing a file that imports `cad_khana` or calls `Assembly()`/`check()`/`inspect()`.
