Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .tuzi-skills/tuzi-compress-image/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.tuzi-skills/tuzi-compress-image/EXTEND.md" && echo "user"
