Why: The first commit picked up __pycache__ created while running the
house-style suite. Bytecode is not part of the skill and should not be
seeded or reviewed.
Evidence: git rm of the cached pyc files; .gitignore now ignores
__pycache__ and *.pyc.
Impact: The skill tree contains only source. Seed already skips
__pycache__ directories.
