feat(skills): drop description column from skills list

Description is agent-facing routing metadata, not a scannable list
property — Linear's display options expose no description column for
the same reason. Removes the cell, column key, display toggle, lg grid
track, skeleton cells, and the now-dead table.description /
table.no_description locale keys.
