Add the 19" rack adapter CAD package and the v2 plan

cad/ holds the left/right side adapters that mount the GeeekPi 9" 3U touchscreen (a 10" mini-rack part) into a standard 19" rack: OpenSCAD source, STLs, Anycubic Mega Pro gcode, and SendCutSend DXFs for the sheet-metal version. Geometry is physically tested in a 19" rack. notes/PLAN-v2.md is the reviewed plan for the Rust rewrite. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
