Four front ends

Four entry points look like four products. They share one engine.

Helpers stay in the scripting language (``lua/dseams.lua`` here,
Python helpers in pydseams). The compiled module is the registration
surface (``dseams_core``, ``pydseams.yoda``).

YAML plus globals (``readFrameOnlyOne``, ``trajectory``,
``functionScript``) is the 2020 / ``seams`` driver contract. A library
script never sees those globals unless the host injects them. This
tree does not grow a second CLI.
