With Jetlink running the big model (on, supported, no Chestnut), Active Big
in Galaxy and on the device is Jetlink's choice: the model manager marks a
big model selectable when its catalog entry names the ONNX it was built from
(source_sha256), downloaded or not, since Jetlink's host fetches the ONNX
itself. The choice is the new JetlinkModel param, {sha256, displayName}, the
adapter's big-model key; Chestnut's own Active Big is left as it was. None
leaves the model to the Jetlink app, and the manager words it.
A newer choice made in the Jetlink app is written back into JetlinkModel by
jetlink, so Active Big shows the model that drives; one StarPilot does not
list is named as the app's.
JetlinkModel is a new key in params_keys.h: the native params libraries need
their usual rebuild.
Own model discovery, compilation and registry selection through explicit model metadata and geometry contracts.
