Let a model say what it is for

A gateway serving nine models offered nine names and nothing to choose between
them. /v1/models is the only view most clients ever have, and it listed ids.

Models carry a description now: written when the model is added, shown on the
dashboard and sent to clients in /v1/models.

Written rather than derived. A registry offers a pipeline tag and a wall of
README, and neither answers the question somebody picking from a list is
asking — which of these should I send this request to. "General chat, strong
Swedish; slower than the 8B" is not in any metadata field.

It is optional, and absent means absent rather than an empty string in the
response: a model nobody described should read as undescribed, not as described
with nothing.

On the dashboard it sits under its row rather than in a column. A sentence in a
table cell either wraps every other column into a stripe or gets cut off.
