Zookeeper generates spiky arcs instead of smooth

[max-mrgrsk]

there are many ways to fix it

• make smooth toggle (seems to be hard) line-arc tangent constraint smoothness ezpz#245
• add reverse toggle on arc (seems to need instruction from ai when to do that, and if the instruction exists, reverse is not really necessary since ai can just swap a and b in code)
• use ai tools, similar to area to check status of tangents spiky/smooth/both https://github.com/KittyCAD/text-to-cad/issues/3638
• use sketch snapshots Add KCL sketch SVG rendering #11763
