Closes #2 — FreeCAD client code belongs in silo-mod, not the server. Remove pkg/freecad/ (16 files, ~4,500 lines): - InitGui.py, Init.py, silo_commands.py, silo_origin.py - package.xml manifest, 10 SVG icons - HolePattern.FCMacro The FreeCAD workbench now lives at: https://git.kindred-systems.com/kindred/silo-mod
