Import the installed SDK
Use `telion` for new scripts and retain `telion_api` only where compatibility is required.
The telion facade is the canonical user import. The telion_api package remains the compatibility surface, and both surfaces are enumerated from their installed __all__ declarations.
import telion
from telion import Model
assert "Model" in telion.__all__
model = Model()
assert isinstance(model, Model)
