The Create module (src/Mod/Create/) was never included in the build
because src/Mod/CMakeLists.txt did not call add_subdirectory(Create).
This meant:
- Mod/Create/InitGui.py was never installed, so the workbench loader
(setup_kindred_workbenches) that loads silo and ztools never ran
- The install rules for mods/silo/freecad/ and mods/silo/silo-client/
never executed, leaving the silo workbench files missing
- kc_format.py was also not listed in the Create install rule
Fixes the 'Ignoring unknown SiloWorkbench' error on startup.
