geodesic-dome-mcp imports numpy + PIL at module load (not stdlib-only, as
#178 incorrectly stated). A present python3 therefore proves nothing — the
preflight would pass on a host missing numpy/Pillow and the tool would fail
only when the MCP host first invokes it.
- setup-mother.sh: add a 'python3 -c "import numpy, PIL"' check after the
python3-exists check, with a pkg install py311-numpy py311-pillow hint.
- MOTHER-SETUP.md: correct the prereq from 'stdlib only, no pip' to
'python3 + numpy + Pillow'.
