Moves the 3D-export bake handlers out of main.cpp: --bake-zone-glb --bake-zone-stl --bake-zone-obj --bake-project-obj --bake-project-stl --bake-project-glb The STL + GLB project bakes share a combined dispatcher (one function with internal STL-vs-GLB branching) since they walk the same per-zone asset list and only differ in the output emission code. main.cpp drops 12,119 → 11,261 lines (-858). The combined-OR opener spanning multiple lines created a parse-error fragment in the extraction; caught + manually fixed before commit (same pattern as the WOM info attachments/particles/sequences extraction).
